(1) The register for a mail ballot election shall be similar to the register for a regular election except that:

(a) it need not have a place for the elector's signature since the elector is required to sign the affidavit on the return/verification envelope instead;

(b) it should have sufficient space to record such information as the return of each validated ballot and the issuance of any replacement ballots; and

(c) it may, where voting is allowed for qualified electors who are not registered, include addendum pages on which to record the names of any such electors who are not known to officials at the time the register is prepared.
