Hey, UpCodes cofounder again, yes, they do ask volunteers to sign a copyright form. You can see it in this ICC tutorial (at 24s): https://www.youtube.com/watch?v=9hebfUQ-G24

Very interesting about that document. Yeah, none of what ICC is doing fits at all with their stated mission or anything.

I'm bookmarking that to read more carefully. Won't help with the lawsuit, but might make for a good tweet.
