When I respond to an incoming message using my wife's mac air, my outgoing message picks up her email address, not mine. She has nothing to do with the reunion and her email address is nowhere on the site. Somehow the computer knows her address and uses it for message center correspondence. Seems very weird. Any thoughts? Thanks, Bruce

I am not sure I understand the problem.

Could it be that your e-mail program's address book has your wife's name associated with the class website's e-mail address?
