I hope you're joking...... cos your comments came through fine.... and are on the website now.
The 'code' is the three-letter 'captcha' image that should appear just below the comment box. It's designed to stop those darn 'spambots' that otherwise clog up such online forms - and it was working OK the last time I looked...
Where does it mention a newletter..... ? - can't remember putting that in there...
