A userbox is a small coloured box (see examples below) designed to appear only on a user page of a Wikidata-contributor as a communicative notice about the user, in order to directly or indirectly help contributors collaborate more effectively.
The first userboxes were introduced to support the Babel, which eases item-translation by allowing the user to view and edit more than one language in the Wikidata-interface.
Other userboxes can indicate WikiProject participation or indicate proficiencies or interests of a particular user. The userboxes might also indicate a users special editing privileges such as administrators, property creators, or bureaucrats.
Please create userboxes in this namespace "Template:" and place a link to the template on this page. If you can, please make them translatable to keep Wikidata multilingual.
