I'm trying to think of a catchy word to use instead of a study/learning groups. The word is used in an informal context and I'm trying to think of something creative.
Something along the lines of 'circles' etc.
EDIT: I thought I'd provide the context to help people. I'm creating a very basic academic social network for my University where users are added to their course 'study groups' but are also free to create their own groups. I like the Google+ circle idea, but I don't want to rip that off.
