Hi Ruben and thanks for the reply.
I should have mentioned this but thought it an extraneous detail. We also have a group called "Newbies" that new users are put in which has the interval between posts set to 5 minutes (this has done wonders to decrease spam "drive by attacks" where they hit every forum btw). The "Users" group therefore has 10 in post count so Newbies are promoted to Users after 10 posts.
Needless to say, most people in Preview have many more than 10 posts so they're instantly put in Users after their first post.
Perhaps it's an either/or choice? Get rid of Newbies so people aren't auto-promoted to Users or not be able to use the Preview mechanism?
