I'm one of the people who does this. Up until your message, I didn't realize that this caused a problem. I guess I was under the impression that threads were defined by the subject and if the subject changed, it would be interpretted as a new thread. If this is not the case, what field is keyed on to determine whether something is a thread or not?
