I haven't had a single comment from anyone on my few postings so far. It makes me wonder if no one is reading, or if they just don't know how to post a comment. So if you want to add a comment:
Click on the "comment" link at the bottom of the post. A window will come up where you can type the comment. If you are not a blogspot member, you can click on the "anonymous" button to submit the comment.
Of course, I guess it is possible that I am not writing anything worthy of a comment. I'll try to work on that.
