Because I want to be able to let them admin a board of their own without having any other powers and there is a mod like this for 3.8 called DTO clubs on drivethruonline.com but I'd like to upgrade to 4.0. I'd have to install a whole new board for every club and that would take a lot of time. Unless there is an easier way?
Why is that? It is simply making multiple boards that are hidden to most usergroups and it only accessible by url then displaying the url. There is no need for multiple licenses for that.
