Hi :) To make a mailbox all you do is go to the Member mailbox board.
Click on "New Discussion"
Make what you want to be your Message :)
Click send message :)
Then
Click on the place at the top of the message that says ""
This will send the messages left for you to your regular email :) :) :)
Then when you get a message you leave your reply in the person's mailbox that sent you the message :)
I hope this makes sense :) If not please let me know :) Also you can have me or anyone you chose to make you a mailbox :)
Please feel free to ask anything at all :) :) :)
