I have a third method for people who these don't work on. When I get around to it I will post it up if needed. Also, you should tell people to post their stream link in that thread on the forums with all the other ones so people can find it.
This is by far the simplest streaming configuration I've ever used and should work for everyone except XP users, but I don't think we have many of those. If a lot of people respond saying they use XP and need an alternative, then you're up.
People will hopefully send me their Twitch names so I can add them to War2tv, and when they do I can edit them manually into the op of that thread (also add them to the site).
