Day 1 on Chess.com

I signed up yesterday, played a game against the computer and lost, looked at some of the lessons... played a game today and won, but wasn't logged on. Went back to the lessons, weren't able to play the videos...

Is there a getting started guide that I've missed?

Thanks.

Welcome to the site. Most of the videos are for diamond membership only. 

Understandable. 'How to play' was a good page, then went on to YouTube for a bit there. I'll be back.

I enjoyed my trial game, appreciated the tips, and won.  It was my first game ever.    This system does not resemble my trial game so I am cancelling now.   Too bad. 

excellent

Ok, gotta start thinking several moves ahead on the puzzles. 

So, I played a bot and won, but had a few moves listed as mistakes. How can I post that board and move so I can ask why it was called a mistake?

Thanks.
