New Double Issue of JCMC

There's a new double issue of the Journal of Computer-Mediated Communication on "Online Communities" and "Computer-Mediated Collaborative Practices." Give it a read if you're interested in one or more of those topics. In the latter theme, there's an article on the use of IM in collaboration. I had hoped to see a case study of wiki use as well, but maybe no one submitted one. At least Wikipedia gets a mention in the introduction to the "Online Communities" theme.
