The best way of finding things like this [i]is[/i] to actually search, but at the same time there's no need for anyone else to be rude about it. 

I took the liberty of searching some of the interest checks and recently started OOCs to find some. This list might not be comprehensive however, but it's something. All of these are rps either in the interest check phase or recently begun their OOCs. There are some longer lasting rps that also tend to be accepting of new players, but that's something you'll have to ask them in their oocs, which you should do in any rp either way.
