How do you start an RP on twitter?

Joing role-play altogether confuses me, but I know its a really fun concept for those who actually know what they're doing. On Twitter, I would set a role play up around a hashtag, like a chat room. You'd have to invite people you know or advertise on a role-playing website, or somewhere like fanfiction.com, depending on the kind of role play.
You might decide your characters and other important factors around a different hashtag, or on another media entirely, like email, and then move to the "real" hashtag when ready to begin.
You could always advertise at the end of other role-plays you've participated in, and say "I'm starting a new role play, at #thisparticularhashtag.
And lastly, how do you find the role-plays you participate in? If you make yours accesible the way most others are, then you should do just as well.
