photos, playing games, chatting, and of course, sharing status updates. Now, the company is giving students a reason to visit that's actually related to academics. 'Groups for schools' creates a virtual venue for collegiate collaboration, letting students and faculty members share un-copyrighted files within the groups created for their sports teams, clubs and even individual classes. There is a file limit of 25MB in play, so consider those dreams of sharing videos and zipped up apps crushed -- you'll also need to provide a .edu address that matches the school before Facebook grants you admission. At first, online cliques will be limited to colleges in the US, though global institutions will eventually be permitted to join in on the fun as well. In the meantime, who knows -- perhaps Dropbox will also launch some kind of super-secret, exclusive club in the near future.
