I have discovered unions. I nticed a few invites and accepted one. Now, I have joined three unions: The Kingdom Hearts World Union, The Dragon's World Union, and the Nickel Storm Park (NSP) Union. I have also applied for the Christian union, but I haven't gotten a message yet.:? I don't plan to join any more, but these are pretty great.
EDIT: Now I have joined the GameSpot Users Interview Union, and I'm an officer!:D
