I just got the email regarding Thinkbox at SIGGRAPH 2011 and it mentions Deadline 5.1. Is there a beta underway, or has the development process changed? Just after DL5 shipped, all of the beta forums vanished from view (for me at least), and this was the first I’ve heard of DL5.1. I hope I’m not missing out on some beta testing 
Hey Phil,
The beta should be starting up closer to Siggraph. We’ll be making the announcement on the forum when it is available.
Cheers,
