This is cool. CAM(era)-(COMM)unity. A project by the Graduate Students' Association here at UCalgary. Not just a "create a profile and post a photo" site - but a physical token that must be passed from grad student to grad student to unlock a login to the site. An interesting way to get students to meet each other, and also to share information about themselves and their research.
