What do the stars mean in some members' profiles?
If you open up a member profile and click on the Groups section, you'll see different stars next to groups for some members. This refers to their admin privileges for each of those groups.
No star = regular member
Blue hollow star = Note Sender
Blue solid star = Group Admin
Gold star = Super Admin
Because Super Admins have all privileges in all groups, you will see a gold star next to all of the groups that they are a member of.
