[Air-l] Greetings and Games

Hello to everyone. I'm a PhD student in Mass Communication at the University of Georgia and have just subscribed to this list. I am in the preliminary stages (read: literature collection) of research project regarding the psychology of, and construction of community in, MMORPGs (Massively Muliplayer Online Role Playing Games). I was wondering if anyone knew of any academic studies of online gaming (in any context, not limited to the ones I described). I've only managed to find the works of Nicholas Yee regarding MMORPGs and Ever Quest in particular (but none of those have have been published anywhere despite being rather extensive). Any help/advice is much appreciated. Federico de Gregorio
