With CR2Edit, it might me because Dan has a constant stream of updates to the program. Although, Render gives vendors access to customers' e-mail using the address registered here, it can only be gotten at from here. Some of the addresses bounce. Maybe DAZ is not so forthcoming or maybe Dan wants an up to date address book on his system. While I am willing to say "feces happens" when someone is paranoid about communication, could be that Dan really wants 100% contact with valid customers. He does a lot of updates, especially since we keep finding new things to do to Poser.
