Hmmm. I'll have to think about this. PM's will be useful instead of passing notes. Mahz was going to make a dice-rolling app at one point. And there is a tabletop section now.
The problem comes back to the difference in speeds between typing something and saying something.
And with some other things, like badges you can't see the other side of.
And Character sheets you can't see the other side of.
Yet I think it's possible. I'm very full-up on RP's right now, however. I'm not sure I could GM another.
