So, I'm making a private forum for the 7th-12th grade in my town (about 500 combined) using freeforums. Whenever I make a category, it doesn't show up on my forum. Am I overlooking something?

I've only used invisionfree, but it had viewing/posting permissions in the admin CP. Maybe you need to edit those.

Looked at the permissions, tweaked some stuff, still couldn't strike gold. Perhaps a member of the staff can do me a favor: log in as me and help me with the ACP?

I could give it a shot. *hopes not to break anything*

If possible, make backups often!

I hope it works and I would check it out when its done.
