bobbieann, Barb has given you a good answer - you can also click on their name - if you see it in a posting or something like that - when you do that - their name will come up and underneath it - will also be a button that says PRIVATE MESSAGE - click it and type your message. *4U
Click on "private" then enter the screen name of the person you want to send to....type your message and hit send...Usually the person receiving the message will notice the +1 next to private and read your message...If you know they are here you might want to alert them of the message in community....Hope this helps YOU:)
