The profile of Linden Lab employees shows that they are employees, all others are residents.
But what about Moles, for example? They have the blue chat color, like Linden, but no entry in the profile.
Mentors should also have an entry there. Mentors do not have a special color in the chat like Linden or Mole, they have no way to show that they are official helpers. An entry in the profile would inspire trust.
