The problem is, is I can't set anyone up as a moderator. I give a user moderator rights, then go into the Manage Forum area, and set the forum to Moderated. However below that, where it list the moderators, I can't type any names in. When I click the magnifying glass to search for a user, to add them as the moderator, it says /DNN Aplication Error. How can I fix this problem?

Also, where would I go to find the Forum_Container.ascx file at? I want to change it from "New thread" to "New Post" I have searched through the host file manager and also admin file manager, however can't find the file module directory.
