This template is intended for use at Wikipedia:Changing username/Usurpations. See Wikipedia:Changing username/Assistance for further information.
All parameters are optional. Using no parameter equals "((CUU|dcontribs=check|notified=yes|email=no))". When the username has contributions, deleted contributions, logs or is less than 6 months old, only one parameter ("contribs=yes", "logs=yes" or "new=yes") is used, the others will be ignored. If you have sent an email to the username, use "email=sent".
