MyBB Community Forums

Basically, I want it so that guests can see all the threads however as soon as they try to open and read a thread, they are prompted with a login box. Currently, disallowing guests from viewing threads makes it as if the forums have no threads at all, which is quite useless in my opinion. Any ideas?

try to see if there is a plugin for it

I have yet to come accross one.

Then you should request one
