Duplicate Email address error message

Hi - I am with club 6026, website address:http://sarasotaevening.toastmastersclubs.org/
I have a husband and wife in our club who share one email address. They are retired and no longer have any other email addresses to use. I get an error message specifying the line number and "duplicate email" when trying to assign the same email to both. Is there a way around this?
Thanks,

Sorry no.

Just add one member without an email address and the system will generate a dummy email for them.
