Bright Kite Groups

I think having groups/communities would be a great way to organize Bright Kite. I like the site, but a lot of my friends are people from forums that I don't recognize their new user names. So maybe a way where people can join a group and see other members to separate from real life friends. Possibly even maybe like categories that we can categorize users. I also think having it display names like twitter or other sites would be a nice addition. Also, does the happening around me function actually work, cause it doesn't seem to show people in BK universe that I know are near me.
