MyBB Community Forums

I have a bunch of groups on my forum, most of them wish to hide their contents from non members but want to show that the group exists.

Is it possible to show the forum link on the index, while hiding the threads and posts. And even linking them to a specific link on the forum (ex. recruitment page)

go to that forum's settings and in permissions tab, uncheck "Can view threads within forum?".. that will hide the threads within the forum although the forum will be visible on index...
