Below is a brief list of useful websites that might be helpful for new players in particular.  It's just a start and we'll welcome your suggestions for links to sites that fellow members might enjoy to help them improve their skills.  There's so much available on Youtube that recommendations are gratefully welcomed.  

There are ads on Youtube that we can't control, but you may be able to skip some of them.  I suppose we wouldn't be able to enjoy the videos without them.
