See additional info about members in facebook groups, and also add your own info. A small icon will apear next to their name.
If you use facebook groups and you want to see more info about each user, you can use this extension. In the next versions you'll be able to edit your info for each group separately. When you're in a group, you will see a small icon next to the name of users who also have the extension. Just put your mouse over it.
This is a Beta version, so please contact me if you have any problems or questions. firstname.lastname@example.org
