 | This page is not a sandbox. It should not be used for test editing. To experiment, please use the Wikipedia sandbox, your user sandbox, or the other sandboxes. |
 | This is a documentation subpage for Template:Template sandbox. It may contain usage information, categories and other content that is not part of the original template page. |
 | This template may have no transclusions, because it is substituted by a tool or script, it is used as part of a short-term or less active Wikipedia process, or for some other reason. |
This page is simply a sandbox in the template space. Put differently, it basically means that this is a place for others to experiment with the template namespace.
