Hmm, that explains the spam increase I'd been griping about, too.

But Chad, I didn't sign up for the Yahoo group and I don't want to register
with them for a password, which seems to be necessary for me to change
my 'membership preferences'?!?

If I'm wrong about this, let me know how to effect this change for myself.
Otherwise, I think it should be your responsibility to correct this for
every
member for having listed us publicly.
