Examples of some famous personalities:
Traken: Infamous for closing threads. Often closes at the height of the fun.
Chaos(of the Right): Claims to be a moderator of Chit Chat but does next to nothing. Argue with at one's own risk.
Erwin: Only 5-green-star poster below the age of 7 years old. May attempt to leave, but always finds himself back at BF. Often is a pestilence easily rubbed out by large amounts of people talking against him.
Smoothware: Notorious spammer, also rather handy with a Photoshop program. Known for barely-legible posts, but lost his red stars in the Great Wayltn Thread Closure.
Gorbet: Forum's only true Australian member. Beware his Aussie-speak, it will corrode your brain.
Doombringer64: Incredibly satirical, fondly known as the Forum Jackass.
Kenji: Also known as the Forum Jackass. Sarcasm is second to none, but occasionally shows spots of brilliance when he tries to help people. Which isn't very often. German background may explain this phenomenon.
Chaos- mod. Serious asshole. Will debate even when there's nothing to debate. Possible cause for "brain drain" of BF.
Dark Magneto- Conspiracy alarmist. Now enlightening the masses about peak oil.
WinAce- former member, but does chime in from time to time. Very fucking smart. Basically the closest to an atheistic apologist.
Redcloak- admin. One of the few ones left (the others were banned in a huge event), basically just posts pictures in the chick thread.
Protosschick99- former member. Crazy Christian fundie. Also one of six females to post on site.
Jedi_Templar- yours truely. Sees himself as a rebel with a cause, but doesn't make that much of an impact.
