When user registers, auto set perm to enter only specific subforum based on reg email

[cp4]

??

question about permissions

On my forums, I have set it up so that you can only register with a .edu email address ( by putting .com .net .org .biz .us .me and everything else in banned web addresses)

I have a general forums page where everybody can go

Then below I have college specific pages.

.............and I would like to figure out a way so that

john@mit.edu

can have permission to enter into the MIT subforum of the site

but he cant enter into Harvard subforum, or Boston College subforum etc.

I would like this to be automatic, based on their registered email address. (or whatever solution makes this happen) so that when they register with their mit.edu email address, the system is all set up for him to go to mitsubforum.forumpage.edu

is there a way to code the mitsubforum so that it can look at user trying to enter and qualify him? same with a harvardsubforum and so on?

I could just have them manually enter their school name using this

I kinda feel like a douche, I posted because I was sure I couldnt find the answer. Its just knowing what terms to search for. (and actually going through all of my vBulletin CP to learn it)
