Especially to 1tess, for your very helpful and hard to make a mess of it advice for a non-techie like me! I added little stars as you suggested-- problem solved, and I am quite pleased with the result. :)

Thanks again to all for your expertise and assistance!

Do you think that I could add a bullet before each new title, so that it would display with a bullet, or would that look too weird on the title page?

You could use special characters in your title. I believe most browsers will display these:

If you like, take a look at my post here:

I'd suggest something simple like this:
► & # 9658;
(remove the spaces after & and #)

Or if I wrote to WordPress, might they consider revising their format?

When you look at a list of my recent posts, there are several entries that run onto a 2nd line, and no way for a reader to tell that those 2nd lines are run overs, and not a new title. I need to have a bulleted list, such as the one on the example in how to use that widget, so that each topic is clearly marked. Any ideas on how to do this? Thanks so much for any help you can offer. :)
