One one of my site I've got about 35 private allowed member list forums. I don't have the usergroups mod installed (I can never get it to work - seperate issue) and am looking for a way to quickly insert the member id into the allowed member lists without going in and manually editing each forum.
Just figure out the SQL statement and run it X times and substituting the forum number. Just monitor what is changing in the database in your first few additions.
