Hmmm....I hope I got it. I was thinking it would be much easier if I could just change one user to moderation review with the click of a mouse.....I didn't think it would require going into the admin at all
I followed your steps but it might be a little different - don't know if this will work or not;
-Created new group called Moderator Review
-Made user a member of Moderator Review
-Set the Group Forum Permissions on ALL forums for members of Moderator Review group to On Moderation Queue
that works will I get an email notifying me that I need to approve posts when said user makes a post?
