You should be able to go here:
http://www.chess.com/echess/myhome.html
But if you're not logged in, that won't work. I use the "stay logged in" feature. Though I also never close my browswer so chess.com is always up somewhere. From any chess.com page you can click on "Online Chess" in the "My Home" menu on the top right.
Being new here, I bookmarked what I thought were the pertinent pages, including those on which my online games are being played. It seems to only way to access the games and get them to [i]work[/i] is to go through the home page and click on the PLAY button. Is that right?
