When you're editing an outline in Fargo, the Eye icon may be available in the left margin. If it's a named outline, the Eye points into the named site. The eye knows how the site-building process works. If it's not a named outline, and you're syncing through the html folder for the outline, you can enter the URL of the home page in the CMS panel of the Outline Settings dialog.
Fargo automatically generates a name attribute for every headline with a type. This allows you to change the text in the headline without breaking links. You can edit the name attribute manually using the Edit Attributes dialog.
