Oh yeah, I have a new idea again which is very slightly based on these other two that I want to write down before I forget. And when I say slightly, I do mean [i]very[/i] slightly

How about an RP forum RP? It's basically like your characters from other RPs can access a dimension crossing forum, and they basically just talk about problems from their own RP with characters from other RPs. This idea I kind of do feel like doing except there's not much point to it and I don't think many people would be very interested.

I think there was a manga about something like this except it was adventurers and not RPers, but I forgot the name of that so I wouldn't be able to reference anything.
