I've done multiple searches and can't seem to find an add-on I'm looking for. As a matter of fact, I think there are 2 or 3 of them. It's an/the add-on(s) that restrict a non-logged in user's ability to just surf the site over and over again (a single session) and not post. After a specified criteria they would get a message telling them to register or sign in. Thank you.
