In case one wonders why did not I, being the Plaintiff,  fill the summons myself, it is because the instructions on the court's website stated that the Pro Se Intake Unite ,which I was required to send my complaint to, "will complete both" the summons and the civil cover sheet for Pro Se litigants filing by mail.
