For the past 12 hours or so, all Blogger blogs were "read only" as Google did some sort of major maintenance. I am now able to post again - some of the recent posts are gone, for now. Google says they may be coming back, but who knows. Also, disregard the "Bad Account" message that you get when you first come to the blog. I am not sure where this comes from or what it means.
So, thank you for your patience. There may be some more hiccups to get through before all is back to normal. I will keep you posted.
