Someone (probably you, from IP address $1) requested a new password for MurrayWiki ($4). A temporary password for user "$2" has been created and was set to "$3". If this was your intent, you will need to log in and choose a new password now. Your temporary password will expire in $5 days.
If someone else made this request, or if you have remembered your password, and you no longer wish to change it, you may ignore this message and continue using your old password.
