I'm not sure I see a problem. V4 has been out for at least eight years. Dawn has been out for just under a year. V4 didn't take over in a year either. I don't personally use Dawn, but I'm sure you realize that I'm a Roxie junkie by now. Plus, Dawn faces challenges that V4 never did.

Besides, most of the people who were really into Dawn have pretty much abandoned the Rendo forums and and are doing a  lot of posting over at Hivewire.
