I dunno how much this helps, but you can still have private RPs on Mems' forums. Just specify in the title and a note in the beginning of the first post that the RP is private between yourself and whichever user you're RPing with. There's also a private messaging system on the site if you'd rather use that.

No one's really done that just yet over there, but private RPs weren't unheard of on our old RP board from forever ago.
