Krepta3000: I see from your profile that you played a game after you posted the question, so I guess you figured it out. Good that you asked, though! Sometimes newcomers start several games and then leave the site without making a single move. Maybe we need some kind of introductory text to explain the basics. Some basic hints like:

- You move by clicking the piece you want to move and the square you want to move it to (or in some games, just the square)
- You finish your move by clicking "submit"
- You can read the rules by following the "show rules" link in each game
- You can see a list of all your games on your "Main page". There's a link to the main page at the top of the left side menu.
- You should always check the time control before you accept a game and make sure it's acceptable to you.

Maybe I missed something? Anything else that would need to be on such a list?
