The news box in the upper-right-hand corner of Movable Type's main menu is pulled over the web from the URL in this value.

You can set this box to display a custom "local" news feed (for example, your organization's internal news), by changing the NewsboxURL value. The content returned at that URL should be a small amount of balanced HTML which will fit within a document object of a varying width.

Use the special value "disable" if you would prefer that MT did not fetch any news in this location.
