So, Join.Me. isn't letting me actually use it at the moment, so I'm scrambling to figure out how to use Livestream. Sorry for the last-minute notice, but they kind of decided to be enormous douchebags to me at the last second.
Also, I prefer XSplit over Livestream's Procaster. The free version doesn't have any real limitations in terms of just streaming art and can stream to Livestream as well. I hope some of this info was helpful. :)
