I'm about to join the "not any mores." I've had the account since 1992, and it's been nice having an email address that stayed stable that long, but their policies have been driving me nuts (they filter for spam -- according to THEIR OWN criteria [one of which is "comes from attbi.com"] -- which cannot be reset by the user) and they've had too much unscheduled down time lately.
I wouldn't have minded this particular instance, if they had messaged their users on Friday with the same text you found, which apparently only GUI users got to see, not us old-fashioned shell accounts. I'm sick of it. I'll keep my $200/yr for something else. (GRRRR.)
I hope to grab my mail, and I hope to actually uns*b my lists subs that go there, but I'm outa there either way.
