Anne, the special tag    can be used to feature only the one custom widget defined at MediaWiki:Widgetwikipage

If an admin creates a new wiz-bang widget at MediaWiki:CustomWidget2 there is currently no way to feature that custom widget using the  tags at either Special:Widgets or Special:WidgetDashboard. If you have discovered a workaround then please share it at: Forum:How to .. provide a custom widget for visitors to use
