How to link a usergroup to a particular forum

[Megatr0n]

Hi,

I'm sure many of you have seen forums where you get a message underneath saying 'Click here for access - where the 'here' is a link. You then select which, group you want to join then a mod will either accept or deny your request.

Now, I know how to create a usergroup but my question is HOW do you link it to the forum where the users have to click in order to make the request? I've asked vBulletin customer support but even they don't know.

Can someone help?

Bump.
