If you've wanted to post comments and you've had trouble with Google registration....you're not the only one. I couldn't access the blog for an hour today due to an impenetrable Google account access problem. Other bloggers have had difficulty (see this), and, if using Microsoft Explorer, have gotten around it by logging in from a different browser, such as Firefox. Might be worth a try. Many apologies for the inconvenience. Blogger has been migrating to a new system, resulting in glitches, and this is one. I encourage your comments, and hope you will persevere.
