Google *really* must do something about those captchas (word codes to commenting). they are usually just unreadable. How can it escape them that everybody is complaining about them? (So we're caught between a wok and a fireplace, either accept spam comments, or keep out the good commenters with bad codes.)
Dave T urged me to try the audio option. And he is right, amazingly, the audio version is even worse. Sounds like a ghost in a bad horror movie, in a bad VHS copy of a copy.
