Postnuke does not have an inbuilt forum - PHPNuke recently changed theirs from Splatt to PHPBB and created a mountain of problems. I know this first hand as I host a German seaman's site on our server and have seen the tears when the forum loses posts.

We now have an addon for a forum with GL which I think is a better solution as not every site wants to add a forum anyway. How many users of GL use every inbuilt facility. There are many that I have disabled and would not use. I use GL as it's interface is easier to use than most others - try adding pictures to a PHPNuke and Postnuke site at 2 am in the morning when you have been at it 16 plus hours.

Yes, I have found numerous faults and shortcomings in GL but feedback from users may remedy this in future issues along with further items I won't use.
