The List Builder is scheduled for retirement on Jun 28, 2019. At that time the List Builder in Webtools will be unavailable and no new content can be added or edited. Public Lists and Widgets will continue to work until the decomissioning of the service on Sep 27, 2019
LAS units Lists are being replaced by ATLAS. Other units may contact Web Services. If we can help we will, in some cases it is possible to convert Lists to Blogs. In other cases it is not possible.
