So I've noticed that the RPs are divide by a "free/casual/advanced" type system, but to me that tell me very little about the type of RPs I actually write. I think it's more important to know the type of story than the minimum requirements of the RPers.
So I think it'd be better if it was divided by genre in addition/instead of by minimum post requirements. Sci fi RPs and fantasy RPs and fandom RPs should more or less be easily segregated from each other, so that I don't have to filter through a hundred RPs in genres I'm not as interested in in order to find the ones I am.
etc., the list can go on if need be, but those ideas I mentioned make up the majority of the different types of RPs I've seen. But one guideline I can figure is that if an active RP gets booted to page 2 or 3 on the list within a single day, that category is probably too large. Except possibly in the case of fandom RPs, there's just so many of them that there's no avoiding having multiple pages of active ones.
