This has to be one of those instances when you wonder why they hadn't done it already, but apparently Google does things in their own time. They just created a dedicated forum for their Chromecast. It's obviously designed to give folks a place to get tech support, info and other help regarding the streaming super-device. There are already FAQ videos and tutorials up and ready for your perusal.
Here's a link for you to check it out: https://productforums.google.com/for...rum/chromecast
Thanks for the tip, Jeffrey!
