BuddyPress.org

I was hoping it was something somewhat easy. I totally think my students would love having their own social network. High school students are familiar with it as part of their daily routine. Unfortunately, I have to host other sites besides my class site. If I could get just to work for http://chargertech.edisonchargers.com/maclab/ and not the other sub-domains, I would be one happy camper.

As for the server. It is a quad-core Xeon Xserve with 4 GB RAM. It is pretty nice for hosting a few class sites, plenty of power.
