There is an interesting feature in Farmville, which is unique - the message board.
This is how it looks like.
Now going to show you the steps of how to create the message board. First you click on the Message Board icon that is at the top of your Farmville screen (after you have logged into Facebook).
You will see a signage as your mouse icon. You will need to place this signage at the spot where you want it to be noticed.
If you have maximized your screen display, you will get a notification to ask you to exit the full screen mode. Otherwise you will not see this message.
You will be asked to enter a message.
Do just that! ;p
Once done, you will receive a notification that you have successfully posted a note.
Click on the signage and then click on 'View Message'.
You will see your message! This works on anyone's farm (yours or a friend's).
Hope this helps!
I love pink roses!
