People were quite upset over 6.6 being available to club members only. The fact that there won't be any public releases until 7, means that custom module, block, etc support is more difficult for those of us without access to the new version. Nukecops, due to that fact, stated they wouldn't provide support for 6.6 which is understandable. FB became irritated by all the negative comments, most likely why the forums there are gone.

As far as Nukecops forking off from Nuke, that's free for anyone to do. They are a great bunch of people, and I'm sure it will be a great product.
