Can't find a modification that allows posting every 7 days?

I notice that some forums have it where you can only post an ad every 7 days. I want to know if this modification is on vbulletin.org and where I can find it?

search (upper right corner) "limit*" in "all mods" "titles only" and you'll find something.

Thank you so much :)

Edit: Nevermind..not what I am looking for. I need it per a forum. Not a usergroup.
