They really have some useful things on their website. Check under for writers. And there are alot of options besides register which can help you out like tools and mentor.
Come october there will be a list of agents and such which are legit within the WGAw. Plan to use that to send some query letters too.
I’ve just tried mentor and hope to get some help with reworking the end of my screenplay.
