TBH, Admins should just do there jobs, which is:
1) Moderate the forums
2) Be active and friendly
3) Contribute to the forums (as anybody/everybody should)
4) Help people in need
Nothing more, nothing less. "Admins should have to contribute to the forums" I agree on. It may sound silly, but Admins should also contribute to the forums. Its more of a role-model thing than anything else, tbh. But honestly, everybody at one point or another should contribute, and being admin doesn't excuse you from that.
Yes, it was stupid to have adam added to the "ADMIN" usergroup, but as @"Glen" said, IT WAS JUST THE USERGROUP! He didn't have access to absolutely ANYTHING but having the usergroup on his name. Nothing special, it was just a few friends messing around with eachother. No need to get butthurt/jealous about it.
@"Chewbaka" Sorry for your demotion, but I wouldn't worry too much about it. You can probably just earn it back. And even if you don't want to, thats up to you. Its not like theres much to moderate on this forums at the current moment anyways. TBH if i got admin, and lost it a month later, I wouldn't care. Being admin is just all for show, letting people know who you are and what you can do. Powers don't earn you respect, or at least I don't believe that.
