Whenever a party by whom or on whose behalf an initial paper is offered for filing is not
represented in the action, such party shall maintain on file with the clerk a current address at
which all notices and copies of pleadings, motions or papers in the action may be served upon
such party. Service of any notices, copies of pleadings, motions or papers in the action at the
address currently maintained on file in the clerk's office by a party shall be deemed to be
effective service upon such party.
