Since I'm the only admin here right now I can't really follow the procedures that the nice new shiny rules say we should follow. However, they do say that the admins can appoint a forth administrator, and I'm the only admin here to make that decision. Therefore I think Carl should become that forth administrator, if he wants to and you guys approve.
About the list, I don't think having seven people that are admins is such a good idea, since there aren't many of us to begin with, but obviously the inactivity of admins is a problem. I may grant several other people moderator powers in certain forums until we have a more permanent solution.
