That's a pity.
What do we do? Well... I've been a member of a few forums which divided due to various reasons. Hacking, ownership disputes, split opinions...
Someone who's been around here for a long time, and is respected by the community, should start another forum. That's what tends to work best - then you have good "leadership" and will garner the technical and financial support from the community.
That's my suggestion. I'll follow.
