Ok, what typically happens is that there's the OOC thread for OOC discussion and annoucements (and idle player-to-player chatter), a Rouge's Gallery thread for everyone's character sheet. I want everyone to post their own so that they can edit them as we progress through the game. Then we have the actual game thread, which I haven't posted yet, as I want everyone's character sheet posted. The recruitment thread shouldn't be used anymore and will die a quiet death.
For more examples of how play-by-post is done, just read some threads on the Playing the Game board. Gru the Wanderer does several cool games, as does Uriel_fire_of_heaven and many other excellent DMs. Give some of those threads a read for examples of play.
