Changing addresses and emails

One of the biggest frustrations in this move to the Forum (other than trying to shelve 70 photo albums and hang 100 paintings) is trying to make address/email changes for organizations, magazines, etc. I've yet to find a form that includes that information slot. I first have to unsubcribe then resubscribe. However, since my old email is no longer active, I don't have a form to use nor do I have the original mailing material so I can include an account number or even the form of my name. There's a big fail here, and I don't think it's mine. Someone in the career field for subscriptions/memberships form design never thought that a member/subscriber would both move AND change the email/password.  Today I was notified of lunch with retired librarians.  My request (I was notified) can't be processed because the listserv (whose owner is deceased) doesn't recognize my new email.

 
One interesting quirk is I think it was one of my doctors' offices did notify the board of elections, something I didn't do. I'm now properly registered.  If I'm not mistaken (will research) my husband worked in the firm that designed/built the school (Winterset in Columbus) where we'll now be voting.
