If you want to preserve history readability (i.e., to have edits from the user to be still shown under their name), you can create a new account e.g. with username "OriginalUserName (deactivated)" and then merge "OriginalUserName" into the former, or even use $1 extension to rename "OriginalUserName" into "AnotherUserName", then create an account under "OriginalUserName" and merge "AnotherUserName" into it: in this manner, "OriginalUserName" will be completely "usurped" (if you've set a non-null password).
