Hi all,

Just a quick announcement to say that comments are working again.

It seems that the captcha plug-in I was using has been discontinued, including the server that validates the captchas themselves. I’ve replaced the old captcha plug-in with one that uses Google reCAPTCHA instead. This should be familiar to most users from other sites on the web. While I don’t like the clunky nature of most captchas, they are necessary on this blog given the amount of spam I receive.

Anyway, apologies for any inconvenience if you were unable to comment on an article. Everything should be fine now.
