The best FPS game ever...

Played it pretty much every day since it was released in 1999, adminned for Truffs and currently Admin for Multiplay.

I've written lots of admin tools for irc-side management of large amounts of servers and evolved what is probably the best ban management system available for Unreal Tournament. This stuff isn't public. :)
(Hint - perl scripts, Xchat and several serverside mutators)

Anyway - bunch of UT related stuff here, including the Aimbot FAQ which has proved very popular - just pick them from the menu on the left.
