How to join after a few years break with a new e-mail address?

I can't change the information for relatives yet they have a new e-mail address so can't get back into geni to do it for themselves? How do they do that?

Patricia,
if they happen to recall what their old password was, they can STILL use the old email address as a login-ID. Geni doesn't care that it's no longer current.
If not, their only option is to send an email to Geni Support ( help@geni.com ), and wait for a reply (can take up to a few days).

Thanks for answering. I'll let them know.
