I'm looking to achieve all of this on a singular install and I need some help My aim is to create a active RPG community as the primary series of categories and forums for my Xenforo install. At the same time I was wondering if it is possible to create say a category or forum and then place it on a subdomain separate from the primary forum. They would in essence exist on the same install, one would be at the bottom and would be collapsed or unviewable to those who are not in a specific forum group. I would also like to know if this section could also have its own skin. Again content overall is the same on the pages, it would just be this part of the forum that would have a separate style and general purpose. Is this possible?
