What? This is a clan member issue not an admin one.
People are going to bash the admins regardless of there being an admin section. Most of the time it is regulars anyway, and they won't have the ability to use that section.
Once again, this has nothing to do with there being a separate section. If the clan members didn't have their own section they still wouldn't be allowed to flame each other.
If you want people to give their opinions then you better deal with the fact people's opinions may be against your idea. I strongly disagree because it will solve nothing. Don't ask for opinions then tell those against to keep their opinions to themselves.
