See posts above.  I basically installed this because it is/was a guild recommended mod for raiding.  Allows main tanks in a raid to be set and provides a ui to quickly access target of tank along with many many other things.  I don't use most of the package and have found a lot of &quot;bugginess&quot; which doesn't impress me a lot, but it works well for the parts I need.  (The multi mail mentioned above thing is a godsend, but I understand that capability will be added by Blizzard with the next major patch.)

[url=http://www.deadlybossmods.com/]Deadly Boss Mods[/url] (used to be called La Vendetta)
This is a fancy little mod that keeps track of and announces (and provides timers) when raid bosses are doing certain abilities.  A user has written an adon for 5 mans as well, but I haven't yet seen this work properly, though I haven't taken the time to make sure I have it set up correctly either.

This is actually a collection of addons which comes with a program that automatically keeps the addons up to date.  (Much like ACE.  And like ACE it provides a set of programming tools which saves memory and makes coding easier.)  It also comes with a UI which allows to to un/install any addons while in game without having to exit.  It has an interface to change options on many of its addons.  It also allows you to easily set up different addons to be used for different chars.  I'm not going to bother going through all the addons which come with [url=http://www.cosmosui.org/addons.php]the package[/url] because the list goes on and on.  I've been very happy with Cosmos and contribute to their cause regularly.  I use about 90% of the addons included in the package.

[url=http://www.curse.com/downloads/details/3416/]X-Perl UnitFrames[/url]
This is a frames addon that I only recently installed.  I've thought aobut installing it for a few years but finally jumped in.  I don't know how I've lived w/o it for so long!  The interface is much cleaner than Blizzard's and quickly provides access to more information.  Includes frames for raid members, party members, pets (including in raids), target of target, target of target of target, focus target and much more.  It's completely configureable and you can choose what frames to use.  It does so many little things that make a huge difference.  Plus, I haven't been able to click on toons in the CTMod raid window to select them for a very long time - the raid frames work perfectly with this addon.  I'm not doing it justice with this explanation, but it rocks.

[url=http://www.curse.com/downloads/details/4204/]KLH Threatmeter[/url]
I know lots of people are saying they like Omen better, but I've stuck with KLH for the time being.  This addon is a must for raiding and, as everyone probably knows, it keeps track of your threat vs others who use the addon.

[url=http://www.curse.com/downloads/details/6491/]DoTimer[/url]
This one provides a window to keep track of the timers of DoT and HoT spells.  As a lock, I find it immensely invaluable to watch when DoTs are getting close to expiration.  It provides times for cooldowns as well, even on useable items and such.  I've used several different mods for keeping track of this information and this one is head and shoulders above the rest.  And it's so configureable.

[url=http://www.curse.com/downloads/details/129/]ItemRack[/url]
Allows you to set up single click options to change gear.  It also lets you program gear to put on automatically in certain circumstances.  ie: Always equip a riding crop upon mounting.

[url=http://www.curse.com/downloads/details/3952/]Simple Raid Target Icons[/url] (aka: SRTI)
Allows a quick selection (double clicking for instance) of a circle of target icons to pop up around a mob to quickly select a target.  It also allows you to promote anyone else in a group who is using the addon so they can mark targets as well, even if they're not the leader.

[url=http://www.curse.com/downloads/details/3893/]EavesDrop[/url]
This is a combat log mod.  It has its own window and simplifies combat log information.  I've tried several similar mods and this one came out on top for me.

[url=http://www.curse.com/downloads/details/2090/]Bagnon[/url]
Combines your bags (or any of your bags) into one large back, basically.  It does the same for your bank bags.  It also allows you to resize the window.  It also keeps track of the bags of other toons on the same account.

[url=http://www.curse.com/downloads/details/6491/]DrDamage[/url] (ACE)
This adds damage and healing amounts per spell on your shorcut bars.  Its theorycrafting is supposed to include all gear etc.  I don't consider this one a must, but I do enjoy the information it provides easily.  This replaced TheoryCraft for me, which is severely outdated.  I think DrDamage only works for certain classes though.

[url=http://www.curse.com/downloads/details/3802/]HealBot Continued[/url]
Basically provides a window which allows you to quickly heal with the click of one of your mouse buttons.  It also tracks aggro and DoTs, curses etc which need to be removed.  It has been an invaluable addon for me while alt+tabbing to play two characters.

[url=http://wwwauctioneeraddon.com]Auctioneer Advanced Suite[/url]
This is the new version of Auctioneer (uses a differenent database than the original), an addon which, in a nutshell, allows you to scan the auction house and keep a database to allow you more easily post on auctions based on past prices.

[url=http://enchantrix.org/]Enchantrix[/url] (standalone or comes in the Auct Adv suite)
Allows you to better guess what an item will disenchant to and whether it'd be better to sell the item or the mats from the de.

[url=http://www.gathereraddon.com/]Gatherer[/url]
Stores information about locations of various items, mainly mining and weed picking nodes, and allows you to see the locaitons on the WoW map.

[url=http://www.curse.com/downloads/details/6787/]ReappearingUnitFrames[/url]
I've had so many problems with my pet bar disappearing or not showing up at all since one of the patches Blizzard applied.  (This has to do with addons accessing secure calls or something.)  This addon keeps redrawing (or redraws on certain events?) the pet bar so it doesn't disappear.  It does the same thing for a few other frames as well.  It does its job well, and I haven't bothered to disable it to see if it's even necessary anymore.

[url=http://www.wowinterface.com/downloads/fileinfo.php?id=4675]ShardAce[/url]
ONLY FOR LOCKS.  Provides a quick and good looking graphic interface for important warlock specific spells.  You can tell at a quck glance how many shards you have on you, summon a pet, create a healthstone etc.  It works a lot like Necrosis in ways, but I found it to be much tighter; Necrosis seemed very buggy back when I used it.  I mainly only use ShardAce anymore to quickly see how many shards I have and as a timer for my soulstone to remind to me use it.

[url=http://www.curse.com/downloads/details/129/]DruidBar[/url]
ONLY FOR DRUIDS.  It does a few things, but I use it to keep track of my mana when in cat or bear form.  It also adds the ability to map special key presses for changing forms, but I've not tried using that yet.  (I got too used to a different addon a long time ago that made shifting forms very easy but the author stopped keeping it up to date.  I haven't used an addon for this since 'cuz it was hard for me to relearn form shifting without one! lol)[url]


When I started out playing WoW and for a long afterwards I was a &quot;plain Jane&quot; kind of a person and was basically against addons.  I finally decided to find out what all the hoopla was about and started with the Cosmos package.  Slowly since then I've become an addon king.  :)

I should note that I've only recently started using X-Perl UnitFrames and don't know what other addons I'm using it mirrors.  (Most of those would be in the Cosmos suite.)  I still need to go through everything to see what X-Perl is just working well with and what it's duplicating.  One biggie outside Cosmos I'm wondering about is CTMod (CTRaidAssist) - I'm not sure if some of the capabilities of X-Perl are duplicating what CTRA does or if it's just working with what CTRA already does.  One day I'll get off my lazy rear and figure this stuff out.

Also, if you find that any of my links are messed up let me know.  I'm not going to try clicking on every one of them to make sure I didn't muck them up.  hehe

PS:  Why the heck is my signature graphic not working YET AGAIN?!!

EDIT:
Added ShardAce - forgot it the first time around...
