Hi John, It's best not to change the subject of a thread, your message will likely not be read by those who are ignoring the Access Technology thread because of how mail programs sort mail. Changing the subject line doesn't change the thread. Sometimes when a thread has been changed, it won't even sort correctly when sorted by Subject. The new message gets lost with the old thread. Make a brand new message and address it to: the group.
