No idea if you're down, but I'd like to get in on your idea if possible. Or just write somethin' else out another time. Whatever works. I dig the character.
Seeing as how there are only three members for the thread I don't think a seprate OOC thread is necessary. It will be easy enough for this amount of people to just communicate via PM or VM.
As for posting order, yeah they usually work out pretty well. Helps people from getting too far behind if say they can't get in a post for a day or two. They can cause things to stall out of one person is holding things up, but if that becomes the case I usually just let the other person know that they're being skipped for a turn or two and are freely welcome to hop back in when they have time.
