I'm going to say use your best judgement. This RP isn't very "open world" so if you post too much to pass the time, it will mess up everyone. I'll leave it everyone's judgement for now. I can think of only one way to post frequently that won't affect the flow of the RP and that would be telling a story to another person, maybe having a flash back to when you could use your powers or something. That's purely up to the writer though.
