This is how the renaming page looks. The form includes a "Current username:" label indicating the current username of the account to be renamed, and a "New username:" label for the requested new username. You need to provide a reason for changing the username in the third input field. If required, check the box saying "Move user and talk pages (and their subpages) to new name". Clicking the Submit button will successfully change the username.
This error message appears when the new username is already taken.
This is the notice of a successfully renamed username.
Usurping an account
This is a process where the username of an account is taken over by another user.
Visit User talk:Dmitriy (usurped)~mediawikiwiki to see usurpation in action.
To achieve this, the administrator can rename the existing username by adding (usurped) as a qualifer. Then they can successfully take over the existing username.
The renaming page looks the same, with one exception, the input field for the "New username:" label now includes the word "(usurped)". This addition indicates that the username is being renamed, so another user can adopt the same username.
This is the notice of a successfully usurped username.
