Private messages

Maybe I'm just confused I don't know. My question is when you recieve a private message and you respond how do you know that your message has been sent?
I'm not sure if I am typeing my response in the correct area.
So sometimes I just click on there name and send then a new private message. Any advice you can give give me would be very much appriciated.
Thank you for your time

Well,

the best way is to click on the box that says "Save a copy of this message in your Sent Items folder."

Then you can look in Sent items, or just copy yourself on the PM....

You will also get a read receipt if you have that box checked.
