vb.org Archive - Age requirements for specific forum

Hi, I have been searching for this modification but with no luck so I thought I'd post a question to see if anyone knows of a way to do this or knows of a mod....

We have a site with probably 20 different forums total. I'd like to make ONE of them impossible to enter unless you agree that you are above a certain age... say 21 for example. For instance, when you click the forum it asks you to validate your birthdate or just simply asks you to agree you are over 21. If you do, it will let you enter. I don't really want it to do this on every visit from the same user, but if that's the only way to go about it, that's cool. I don't want all of the forums on the site doing that... just one, a NSFW section.

Any thoughts/ideas/suggestions? Thanks! :)
