• This template creates a link to a WP:RFCU (checkuser) page on a user.
  • If this template cannot find a subpage for a user, the link simply will not appear.
  • This template takes one expected parameter: the exact and correct username (without the prefix "User:") of the RFCU's subject, for instance {{rfcu-cond|John Doe}}. If this is not provided, the default will be the "basepagename" where this template is posted, for instance the username of a user page or user-talk page.
  • This template will provide a default link label, WP:RFCU page on "John Doe" (if it exists), or else nothing at all (if it doesn't exist). If you wish a different link label, such as "here", provide it as a second unnamed parameter after the username, for instance {{rfcu-cond|John Doe|here}}.
  • This template does not require substitution.
