Learn how to post on walls, post status updates, and send messagesin this Facebook tutorial.
Make sure to keep in touch with your friends by updating your status, posting on their walls and sending them messages. So if I’d like to post something on my wall, I’m going to go to this little box to make a status update. This is also the same box I’d use if I wanted to post something on someone else’s wall. I’m going to say "Loving Howcast Demo" and it’s going to highlight to say that I’ve tagged them in my post, which means if it’s on my friends wall, it will also show up on their wall. Now if I want to send someone a message, I click on their profile and say send message. There you go. That’s how you make a status update, a wall post and a message.
