So, I got an invite to sign up because I'm a large donor and the first two steps were paying a 49.99 fee and signing an NDA. I asked if this is something that would be in place for all users and I was told all users will be signing an NDA, but the fee may change.

Also, in the terms of services you waive the rights to anything you post, and you waive the rights to take part in any class action lawsuit involved with the site owner/operators.

It's interesting! I actually love this model because it retains use for people that are very serious and will eliminate glowies and trolls.
