After uploading, it doesn't show up anywhere for me or anyone else to use. I thought it was a permission issue, but it wasn't in permissions either. It doesn't seem to be compatible with the latest version of Xenforo, and the demo on addonsrus.com doesn't work properly either.
When you install this add-on you need to add your categories just like you would if it was a forum, all media needs to be placed in a category. If you could post the problems you are having it would help me to improve this add-on without this info how can any developer improve there add-on, but thank you for your comment
