Cmail/XBoard won't allow move I've recently started playing e-mail correspondence chess and I'm looking at Cmail/XBoard as a tool to play these games. Looking at the docs, I managed to get the right PGN tags for the game to be parsed and XBoard to launch and display the latest position.

XBoard will not allow any moves though. I can step through the game but not enter a new move.

Any idea on what could be wrong with the XBoard settings or the PGN input?

Once you provide the email file to Cmail/XBoard, you need to switch to 'Edit Game' mode, in the Mode menu in order to record a move. Also, I had to switch out of 'Edit Game' mode in order to mail the move.
