Your message entitled “How to read/write an int in binary form to a
file?” was sent in reply to a message with a different subject. You
probably intended to start a new thread; however, your mailer, like
most MUAs, tricked you by including a References: header field which
points back to the original message.
Therefore, your new message is still threaded under the original
subject, instead of your new subject. Unfortunately, this can cause
your message to get lost in a completely unrelated thread!
In the future, if you’d like to start a new thread, please compose a
NEW message to ruby-talk ML email@example.com
Thank you for your time and consideration…
