NoKSouLz, Let's say we have six members in three groups:

• White
  • Blue
  • Green
• Black
  • Red
  • Brown
• Gray
  • Yellow
  • Orange

Who is allowed to make friends?
Blue and Green can make friends with other members of the White group ..
Red and Brown can make friends with other members of the Black group ..

Who isn't allowed?
Blue and Green can't make friends with members of groups: Black and Gray ..
Red and Brown can't make friends with members of groups: White and Gray ..
Yellow and Orange can't make friends with members of groups: White, Black and Gray ..

What else?
If Green is a friend with member Blue .. and the Administrator moved Green to the Black or Gray groups; then Green is no longer a friend with member Blue automatically, unless moved back to the white group on a later time.
