-- Links in Section 1a (Pre-made Text Links and Labels) of the Homepage Setup feature cannot be deleted. They may be removed from the Navigation Menu by unchecking the box to the left of them in Homepage Setup.
-- Links in Section 2 (MyLinks) can be removed from the Navigation Menu by unchecking the box to the left of them, but they may also be "deleted" in the sense that you may edit the Name, Short Description and URL destination and leave them blank.
-- Links that you create in Press Articles can be removed simply by removing the Link Name from a page using the Press Article edit feature. This does NOT delete the page; it only removes the link from the Navigation Bar.
