I’m afraid that a continued and increasing dribble of comment spam has forced me to put on the CAPTCHA (completely automated public Turing test to tell computers and humans apart) task so that a commenter needs to fill it in the little box when they’re done. If you have a typekey identity, you wont need to.
Sorry, but I’ve been spending way too much time cleaning out junk, and it only takes a few seconds to help us all out by filling in the box.
If you object very loudly, I’ll reconsider, but I think most people would prefer it this way. (Comments?)
