What is the difference between the two mentioned items in the subject line in the private messaging?
I prepared a message, and pushed send, and it went to my outbox vs sentbox like I would have expected. Does it get to sent box when the person reads it?
In my past experiences with other web boards, the message is moved to the sent folder when the receiving person reads the new message. I look at it as a way for me to see if the other person has read the message yet. If the message is still in my outbox, then I know it hasn’t been read yet. If it isn’t, I know that it has been read.
