Iffin' you note the color of the screen names, the Greenones are paid members.
Signatures , Avatars, admission to meet & greets, shoots, luncheons, the "Members Only" forum and secret decoder rings (No, not really.) will set 'cha back a whoppin' nineteen bucks.
It's worth it, believe me you'll get to come to some shoots, make new friends and generally have a good time.
