I don't know if this has as much to do with the script as it does with me being to blind to see it but by default the forums has the Administrator Group, Moderator, and User. When I go to set a user to the moderator group there is no option only Admin and user. I also tried making another group called moderator and made it so they can moderate all forums but when I put them in that group they could not moderate any forums.
Any ideas? :P
