I think I will use Ning at some point very soon. I like the idea that it's Facebook-ish, and that many students will be familiar with the concepts and ideas that would go into a page like that. I have always wanted my kids to do a Facebook page for characters in a book but don't want them to go onto a Facebook site to do so. Sarah Johnson is doing that same assignment but having them do a Facebook page but just to transfer the information that WOULD be on their Facebook page onto a Word document. This would allow me to do the assignment but in a safe and limited environment!
