The Greyson template features a text banner that can appear at the top of every page to call attention to your latest news, or include links to sales, or whatever you like! To add that to your site, create a page, and in the Page Properties, set the Page Keyword of that page to "bannertext." Then hit Save.
Once you've done that, anything you put into the content of that page will show at the top of every page on your site. We suggest keeping it brief, and text-only. If you want to remove the banner from the site, simply deactivate the page.
