>Naomi, I'm already receiving tiresome e-mails from a certain person criticizing another UT member and would prefer not to communicate with that person any further. I guess I'll have to change my address.

Almost all e-mail systems allow to block addresses. Or you can simply press delete button.

I'm not sure what else to suggest. BTW, PUTMs have an option to hide e-mail address. It's in account setup.
