I would suggest a letter rating system stating clearly whats within the RP. simple stuff like (V) for lots of vore, (v) for a little vore just to divide whats within each RP at a glance. This way people will be able to find RP's they want easier. (B) for blood and/or violence. (CC) for Combat Centered, or stuff with little plot and jsut combat.
I would also suggest creating an archive subforum for character storage so that continuity can be done easily and characters are much less likely to be forgottwen and easier to transfer between RPs. A general Character profile for RPs, with adding extras or removing them based on the RP is also a good idea.
*RPs tooooo much*
Also, make the chatbox open in a seperate window, so ti can be used regardless of page.
