UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support Help! Pass-protected forum still accessible to ALL

Thanks. OK here is my objective..

Private forum that can not be access unless I send you a password.

There is nowhere to state that in the settings for this forum. I mean, I have to say ALL REGISTERED USERS because I don't see anywhere to say "ALL REGISTERED USERS WITH THE PASSWORD"

Help?
