Thanks.
I hadn't thought of that possibility.
So what I did was created 40 dummy addressbooks.
Closed Thunderbird
Renamed the mab files to the name of the 40.
Opened thunderbird
Moved the contacts from the 40 dummy books to the current, current
addressbooks.
Ran "remove duplicates", without looking at what I was deleting.
Oops. It removes duplicate names, not duplicate email addresses. :(
Anyway, I have 200 or so mabs to transfer over, so I'm hoping I didn't
lose too many contacts.
