'Captcha'

With deep irony after my earlier post, I had an attack of the spams today. Some of which made it to the site. So after having a major spam cleanup (apologies to anyone tracking comments via RSS or email), I've implemented a 'captcha'. I.e. anyone commenting must provide the secret password. This is pretty easy for a human - but much harder for an automated script. This is not based on a graphic, but is instead based upon understanding a sentence. If anyone runs into bugs, please let me know on bugs (at) murky (dot) org. Thanks.

It is now also possible to ask the software to automatically email you comments on a post without having to comment yourself.

(Update: This is now removed).
