So I splurged and dropped $20 on the HighDef stream – the goodies will hopefully get me some ISK and, hey, its less than an evening at the movie theater.
The process to get into the subscribed Twitch channel is very obscure and CCP does not help with giving any instructions beyond how to pay. For that they are very good.
So, one you pay, you get a “voucher” from Twitch that you can find in your CCP’s account’s “voucher center”. Copy that to clipboard (or memorize it :)), then go to twitch.tv/ccp and use it when signing in. It will work and when you speak in the chat channel, a EVE symbol will be next to your name.
And thats it – CCP again excels at obfuscating the way things work….
