This site currently receives over 65,000 spam comments each month. The vast majority of these (>99.9%) are intercepted by the excellent Akismet spam filter and so never appear on posts but they are still an unwanted drain on server resources.
I have therefore introduced a Captcha that will need to be completed before a comment can be submitted. No, not one of those that uses impossible to read distorted letters (particularly on hand-held devices) or silly drag-and-drop games, just a simple arithmetic sum as shown on the screenshot below. I felt that this was a better option than requiring you to register at the site and then having to log in before being able to add a comment.
Until you get used to the change, I strongly recommend that before you click on the ‘Submit Comment’ button you right-click and pick ‘Select All’ (or use Ctrl+A) followed by right-click ‘Copy’ (or Ctrl+C). Then, if you forget to fill in the Captcha, you can paste your comment back into the empty text box (right-click ‘Paste’ or Ctrl+V). If you forget to fill in the Captcha, after clicking on the ‘Submit Comment’ button you will receive an error message and you will then need to use your browser’s ‘Back’ button to return to the post.
