The sections I'm thinking of are:
OOC Discussion
Out-of-character discussion; to be clear, this wouldn't be just another General forum, but would contain all out-of-character threads for a role-play, linked to from the main RP thread. This would allow more complex role-plays to have threads set aside for character-sheets, general discussion and so-on. Still nothing too excessive, but it'd help reduce clutter on the main forum which would be for a single active thread per role-play.
Recruitment
Instead of a single topic, a sub-forum would be used for role-play ideas. In this case a games-master can simply post a thread with their idea, and people can reply to it directly with ideas, feedback, or requests to join. This'd probably be a lot easier than the current… well… cluster fuck of a thread
