User registration and/or posting rules by location

[atomhead]

Hello,

I'm looking to create a community site for people in my city. I would like to have a certain section of the site that's only useable by people from a certain location, or possibly even restrict new user registration from outside of the city. Is this possible with vBulletin?

You can restrict access to forums by usergroup permissions. You can decide, who will be able to see certain content (and who won't). Is that what you are looking for?

As for the registrations: How will you identify people from outside of the city? By IP adresses? Well, you can block IP adresses, but I doubt that this will do the job very well...
