Hello all, I recently set up my own forum using MiniBB and I got to say that it is pretty awesome, however I have a couple of forums that I dont want to be seen by guests, is there some way to do this? Also related to this, is it possible to make a moderators-only forum?
Sorry if there is already a topic opened for this, but I dont have that much time to check them all now, anyways I will later.
Thanks in advance.

I would recommend to take a look at major miniBB options described in Manual first, as always :-)

It's all possible with miniBB. To open certain forums for guests, disable or set to FALSE $allForumsReg option in setup_options.php, then set up $regUsrForums array in bb_specials.php like it's described in Manual, specifying forum IDs.

As for moderators-only forum, you may set up the closed forum, setting up $clForums and $clForumsUsers in the format described.
