can't unsubscribe !!!

[Jaspreet Singh]

Hi
	I had subscribed to this mailing list sometime back. The problem is
that my mailing address has changed; i get all the mails sent to my old mail
id but i can't send a mail from my old mail id. So i can't unsubscribe my
old mail id from this list as the mailer daemon thinks that i am trying to
unsubscribe another person.
	Please help.. my old mail id is..  jasingh at quark.stpm.soft.net

Thanks in advance,
Jaspreet
