Going off of Ms.Zhi's idea I think it would be wise to post a side note next to topics that have gotten more in depth. Such as what has happened in the story so far. It would help a lot so that people wanting to jump in don't have to read say eighty posts before they can reply.
Also I think it would be nice if one could create a topic or something for roleplay to, I suppose, max out their personage. Say I wanted to actually rp out what happened in my past....I think it would be nice if others could join in on that following along with the plot. Think of it as maybe...advancing one's personage but in more epic and enjoyable way than just sitting down and writing it out yourself.
No offense to those who enjoy that.
