I am looking for a friend's list  for the Organic Groups module I'm looking for a friend's list (kind of Google+ circles functionality) to work with the Organic Groups module.

I wish to allow users to add tags to users that are their friends, e.g. work or family, and then use these tags for activities like share, privacy, or mailing list.

I didn't find any, but the closest modules are:


Relationships; it is public to other users and has to be confirmed by the other user.
User roles; it is set by the admin
Mail lists; I didn't find any that tag/manage contacts by tags or lists. The Lists module doesn't work well.
You might give User Relationships module a try.

Basically, you can create one way and two way relationships, such as friends, manager.
