I don't have an exact number, no. We have methods of communication that'd make figuring it out way easier, though, so that might be worth a try, come to think of it...

[Filing that thought away for later!]

I haven't really been looking for a way out so much as... going into these things to help find the people stuck in 'em and lead them out. This isn't my first go-round with ending up in a different world, and I know from experience that having nothing in the way of real support sucks. So if I can try to help, I do.
