Just get some program like manycam and an account and that's it.
As far I know -.-

Manycam is like for "Watchtail"and others. Procaster is made for and built for Livestream.

ok.. how is your PC power.. can it handle playing WOW very easy at high settings are not. if it can. Then google up "Procaster" then go to Livestream.com and make a artist account. Log-on with Procaster. In the procaster settings.. go to the audio section.. up top you will see 2 volume slider control bars you can move.. under that is a check box. check the box and now the controllers are now active. Then mute the mic one. find the tab that lets you control the highlight around your mouse and set it to like 10. Back on the first tab is a option to record every session.. I take it off cause your not post to be drawing nude on Livestream im guessing. Plus it helps on speed.

Hope this helps dood ^y^

If you cant handle that process power.. then use the webbroswer controls to setup your livestream to Procaster again. I dont have info on the webroswer way >.<

I highly doubt my computer has the power to run WoW efficiently, but I'll see what I can do. Thanks for the help, friend.
