Is there a simple way to promote a single user to an Administrator? My forums are at http://www.comedycluster.com/forums, and the user is MikeH. I know how to set up a form of promotion by matching a certain criteria, but I was wondering if there was a way to just promote a single user without them having to match any criteria.

In the ACP, edit the user and change the primary user group to administrator.
