Thank you for your reply
I know where & how to set permissions. I have done that a million times over the last 6 years.

But, in vbulletin, there is no settings anywhere that I can find that will allow members to reply to threads in a forum that is closed to new threads.
I want members to be able to comment on threads that are in a closed thread but not be able to create new threads...
Is there an option that I must be overlooking that will allow this?
Thank you
