I can set one up if need be... never used it but im sure I could figure it out.
There easy as dirt to set up. Just click the "start a hangout" link in the upper right of your G+ page. Then it gives you an option to name it (I'd suggest "Brammo Empulse Launch Watch Party") and then it shows your camera's output (usually your face?) and says something like, "check your hair - if you're ready, press start" And you're golden.
At that point, you can add specific people, or make it public, or share it with one of your circles, etc.
If I get my sound issue sorted out, I'd be happy to set it up, but don't wait for me. I'll let you know if anything changes - let's keep this thread as the go-to thread for the event.
