Heading and Subheading text sliding

Hi smottly87. Welcome to the hueman forum. That marquee is not a part of the default theme configuration. You’d need to find out what plugin or other customization that site is using and then enter the appropriate options or make the appropriate modifications to show the post title.

If you search the plugin repository you’ll find several marquee-related plugins.
There are also stand-alone jQuery plug-ins like this one:
