I looked at the name of the postwriter, and at the topic title, and was expecting something far more exciting..... Ah well.
When you post a topic or reply, you will see a little toolbar at the top of the box you are typing in, click the left hand one (chessboard) and it will allow you to setup positions, puzzles or diagrams.
Where can I find the chess board that allows you to show games and create puzzles?
