One person reported difficulty in commenting on posts. Here are some brief instructions:
1. Click on the "comments" (it will say the number of comments already made--e.g., "0 comments") hyperlink at the end of the entry.
2. Click on the "Post a comment link."
3. If you do not have a Blogger account, click on the "Or Post Anonymously" link.
4. Enter your comments and click on "Publish your comment."
This should work. One person has already posted a comment on one of my entries.
Also note that you send links to posts of interest to your friends though the envelope icon at the end of each post. They will probably be very touched and grateful for the wisdom you are sharing.
