Given the board is still excessively light in terms of discussion, I don't see how an unofficial board would be any better except for a handful of posters at best posting (The same ones here). Heck, even the Btsporn board (Sineplex) is dead. These forums could of used moderation when the site kicked in at the start, but those folks either got bored or got banned a while back.
You mention you have exhausted all angles, but which issues are you talking about exactly? Best way to have a discussion is to put it on blast for others to discuss (or troll
). Aside from the usual whining from all sides, it's been pretty calm.
If anything, some of the threads need cleaning (Probably get rid of the mega threads and create a new topic for each one) or merging. That and a sticky thread for FAQs or announcements would be ideal. Would hopefully prevent some of the drastically redundant threads that have been beaten over too many times.
Since discussion is light here, I'm assuming you either don't like some of the stuff various posters say or the forum/threads are a bit messy to your liking.
