Do the free lessons on this site, a couple a week at least, plus have a go at a couple of puzzles a day and enjoy playing people. If anyone is rude block and report. Join a nice friendly club or two as well. Have fun and welcome.
If you fancy a friendly non rated daily game I’m happy with that.
Practically everybody on this site can be smeared by a few names you would recognize. They aren't as good as you think so just do the best you can.
