When you reply to an obra digest, you are sending that entire digest
back out to the recipients of the obra list unless you take the time to
delete the quoted material or unless your mail client is set to not
include the original message when replying. If many people are
replying to the same thread, the entire thread or even the entire digest
can get repeated over and over and over within a single digest, and it
can be difficult to tell when you have left the embedded digest/thread
repeats and re-joined the part of the digest that has new material.
Please take a couple of seconds to delete unnecessarily repetitious
stuff from your submissions.
