Hey, I've lost my little notepad of a discription of places to avoid and such stuff but hey I'll give it a whack from memory (well the basics anyways):
General Chat: Good for a laugh, never overly serious.
Arts and Writing: You can find some really nice stories, artwork and other such stuff here, give it a visit.
Eyes On Each Other: If you don't want to listen to as much of PG's crap go there, their sane and like a good descussion, same with the world events forum.
Game Specific Forum: Contains trivia, hints tips and stuff about future sequals/releases to that game or series.
General Gaming Forum: Example thread 'If all the main characters from FF were to get in a fight, who would win'.
I think that was it, have a great time here and ignore anyone you don't like and hit the warn button else Lezza will get annoyed and club you to death with a cat
