Why can't you assign an identifying sequence number to messages? Once
posted, because there are so many, and because there is such an unpredictable
delay in when they are finally posted, as well as time zone differences, it
is usually impossible to return to them to see if anyone has responded. They
are simply impossible to find. Have you ever thought about instituting
basic usability testing for your products? In this case, it would have
revealed this serious problem.
