Many times, the answer to a given question is available at any number of places. Not the least of which is Apple's own site . If your question is answered there or on another site, don't be surprised if you're just referred there. It's easier to go to the site and read it than for us to type it all out on channel. That's in the manual.
Manuals are highly recommended reading.
It looks like you're all set. Hop in, and don't be afraid. This is an evolving list. Questions will be added as they appear on channel and are answered. Sorry to hear that.
