Turns out that the administrator is discontinuing the email service. If you don't want to use your "regular" email you can create an account on one of the free services and use that. (gmail, yahoo, etc.)
I've never been spammed or gotten unwarranted email from any HW members - remember only members can see your email in your profile - in the over 10 years I've had my email available.
So maybe you'll feel comfortable with your existing email....
