This is a user template for translators and other editors on more than one Wikipedia. It is based on the {{user-t}} template, which is then based on {{user-c}} (a compressed version of the {{user}} template). It has links to both the user's English-language Wikipedia user page, talk page and their contributions, and also to the user's pages and contributions on one or two Wikipedias in another language.
This template is also for users where their user name is different between the Wikipedias, which is common when the other Wikipedias do not use the Latin alphabet.
