Yo! I just wanted to pimp an online RPG design and theory forum. Some would call theorizing about how best to make and play pen'n'paper RPGs extremely pretentious - I would argue that it's the best thing to happen to rolepaying since roleplaying was invented. A lot of the best RPGs and ideas about how to play RPGs that I've come across came from this forum - it's definitely something you guys should check out. It's heavy on the reading, but worth it.
P.S: Start with the "Articles" section - it'll prepare you for the jargon. Then check out the games that have been published by these guys - Sorceror, Donjon, Elfs, The Pool, The Riddle of Steel... and so on.
