The only difference between these 2 groups is the permissions on 2 forums. Registered are not allowed to start threads in these 2 forums. Members can start threads.
This appeared to be working as I've had a test account under 5 posts and it was not able to post. I have looked at the forum as other users who have over 5 posts and they can post. Today I had a user ask me why they can't post in those forums. I looked and they are in the Registered group and secondary Members. They have 285 posts. They don't have any special permissions.
I can't see why this one user can't get in. Is there something I am doing wrong?
edit: I am testing permissions on other users and I am seeing the same problem. So some users can start threads and others can't. Though they all appear to have the same permissions.
edit: I looked in the database and I can see a lot of users who are not in the secondary Members group who have over 5 posts.
