After clicking the Save button Netscape will automatically prompt you for a title for the page based on the filename you used to save your document.  In this case 'boats' is the prompted Title.  But that's not very descriptive, is it?

There, I've entered 'My Pictures of Boats' as the new title for this page.  I probably should have used my name instead, but this is only an example. A good title should be relatively short, but accurately describe what your page is about.
