Well, I am a digital designer, so at my current internship/job I had the luck of getting an old PowerMac G3.  Its only 400 MHz with 384MB PC100 Ram, but it runs MacOSX 10.4.4.  Why am I revealing this?

Well, I am new to owning a Mac, and playing around with OSX (aside from the programs I use at school/work), and I was wondering if anyone could just give me some basic information, or links for good Mac OSX programs like FTP Clients, IRC programs, stuff like that.

Anyone?
