I would love it if you would send it to her too. I won’t post her email address but it is simple to find.

Already did. Also I took the liberty of putting Ms. Okubo's official public email address in my response above for the convenience of others (as of now it has not bounced).

But you really did all the hard lifting on this. :-)
