UPDATE: Technical issues -- troubles commenting

Those of you having trouble posting comments may want to consider registering for Blogger/Google. It is free, and seems to allow one to skip the image verification step that seems to be troubling people. Another thing to try would be lowering your security settings, especially ones governing "mixed content" and the display of images on web pages. Finally, try switching browsers. I use Mozilla Firefox and have never had the slightest issue with Blogger.

UPDATE: I have changed some settings to avoid the word verification hurdle. Let's see if that fixes the problems.
