Did you obtain these legally?
It's not really hard to understand. We allow no discussion of illegal software. If you are an official alpha or beta tester and haven't agreed to any NDAs forbidding it, then post away.
If it's Warez (obtained in any manner other than legally from ID) then the thread will die and you may be suspended or banned.
I'd personally like nothing more than for them to release a Demo, but it ain't happened as yet.
