Postponed: Ameritech NAP maintenance

["Mark A. Cnota" <mcnota () ameritech net>]

As luck would have it, within 90 minutes of my sending a notice out, I was
told the maintenance has been postponed. Timing is everything, they say.

Naturally, we will let everyone know as soon as a new date has been scheduled.

As before, customers with questions can contact me privately.
