Daz isn't big on supporting Poser, but as far as I know, the vendors aren't prohibited from doing so as long as the product has full DAZ support (excepting that I think that if they want to make a Poser shader product, they have to release a Daz version as well, but I could be wrong-- It's irrelevant anyhow since there is no Poser category in the Shaders page.)

Can't imagine SM leaving their official forums on a site now owned by a hostile competitor True. Where will they put them, then? Hivewire? Hivewire isn't going to host "the official" forum for off-site software on their site. So unless SM want to open forums again on Content Paradise, which they no longer seem to care about anymore, then there aren't too many options. The whole point of SM making RDNA their official forum is because they (SM) couldn't be bothered to host it on their own site. Poser is eventually going to fail unless SM get off their butt and stop relying on sales of Poser on other sites (e.g. sales off of Renderosity and RDNA like they do now rather than sales off of Content Paradise)
