Didn't know about this chat room/group feature, that sounds like a low-transition way to solve the problem! (have I ever said I was a skype expert? I sure hope not, because that would have been a big fat LIE,- I'm lucky I figured out how to put my picture in it :D )
Of course, if campfire isso super awesome that we're losing out big by not using it.... ? well, I've never used it, so I have no data there myself.
Here's my proposal: let's see see how this skype group feature works out for us. - If that is proving inadequate in some way (see, I left that completely vague and open), then we can look into something else. Feel free to argue against this suggestion.
