So I'm stalking the MUD community again, and I was curious about Quicksilver Forums and QSF Portal, as I'm spinning up a forum of my own. Sadly the only link that works as you'd imagine is the one for MercuryBoard, which simply points to Quicksilver Forums. QSF Portal goes to a totally unrelated site, while Quicksilver Forums seems to be having PHP issues.
It was more out of curiosity. I've sort of dived into Vanilla Forums - having already studied the framework enough to write a plugin (and working on another). I have a big desire for self-moderation, which is quite possible there.
Just thought I'd toss that out there.
