MyBB or XenForo Integration
Can someone make a plugin that integrates MyBB or XenForo with Fork?
I don't think anyone will do this as we have our own forum module. It will be released in the near future.
Another thing is. If you really want those apps in your Fork site you can add a page and show it in an iframe.
That should do your trick only if you don't want the fork users integrated.
