Nice detective work on the IP address thing.  You sure did a lot of homework looking up posts from Jim Kline, which makes me question your motives.

The IP address recorded by YTMag.com is the IP address of the machine that sent the message, true.  The computer typically gets its IP address from the Internet Service Provider during the login process.  However, the IP address could also be set manually by a user if the computer is behind a router or server.  As long as the IP address is in the "range" that is accepted by the router or server, the IP could be literally anything from 0.0.0.0 to 255.255.255.255.  A savvy computer expert such as yourself could easily set the IP address range of his server or router (anyone can buy one at Best Buy for $40) to the range similar to Jim Kline's, or mine, or yours, or whatever.

So, this leads me to question if Jim really posted that or not.  Again, a savvy expert such as yourself could have:
1. Picked a patsy, unfortunately Jim on this one. (Notice most of Jim's other posts are answering questions to budding Oliver collectors.  Certainly a novel activity by anyone's standards.)
2. Researched some of his last posts to determine the IP range (you spent quite a bit of time on this, and then posted it).
3. Setup your IP address to be similar.
4. Then publish the results and wait for the bullets to fly.

Nice work.  I'm impressed.

Sounds like a "renegade" activity.  Any member aiming toward the club's best interests wouldn't have...
