How can I remove the title of the page from displaying in the main body of the page? That is, my main menu already has a link to the page, and I don't want the title to display again within the content of the page.

There's a couple of ways to answer that question, depending on your particular goals. Here are a few things to try:

If you just want to get rid of the "Home" title on your site's front page, you can do that by going to Configuration -> System -> Site Information, check the "hide page title on homepage" box and then click the "save configuration" button.

If, on the other hand, you just don't want both the navigation menu link and the title to repeat each other (i.e. About as a menu item and a page headline), you can edit the page, change the title to something more descriptive and helpful for your visitors (for example, "About the Urban Economics Lab"), but keep the menu link title as About.

I wouldn't recommend hiding your page titles completely, as they provide helpful information for your visitors. However, if that is indeed your goal, you could use CSS Injector to create a style for the page headline that sets it to display:none or positions it off screen.

I hope this is helpful information.

That was really helpful! Thanks!
