Share 'Anyone using Facebook?'

Hi Everyone, If any of you have pages in Facebook, let me know. We can link as friends. Also, I'm thinking of using Facebook as part of my classes (along with SL, Twitter, Wikis and Moodles). I teach English and Methods at Montclair State University in NJ and would love hearing if any of you are using these other sites and how you incorporate them in your syllabi. -Laura
