Topic: Can User ranks have more or less privaledges?
I've never come across such a thing, but I'm very interested in the idea of having pages that only users of a particular user rank can access. Is such a thing possible?
Re: Can User ranks have more or less privaledges?
Im not quite sure what use you can have from this feature 
However can you not just make a new User Group based on Moderators. Just set permissions to however you need them. Set it so that only users within that user group can read the forum. It would be invisible to guests and people outside of that User Group. It can all be done through the admin panel and is the quickest option.
Maybe someone could create a small mod that automatically adds users to the special User Group when they reach a certain number of posts?
