Add profiles of people you know and enjoy. This list will be shared with everyone else on your fun tree. For example: I add profile A, B, and C to my fun tree. If profile A views my profile they can see that I have listed profiles B and C. Since profile A already knows me they may just want to get to know the people from profiles B and C. In order to view your fun tree, you must add yourself to it.
A little warning... a message is sent to the people you add, so you should already know them before adding them to your tree.
You can add comments about the profile that added you to their fun tree, and you can make comments about the profiles you add to yours. The Fun Tree is a mini-networking feature that lets your friends know about others whom are your friends as well! Please, don't leave negative comments! If you have negative things to say, don't add the profile to your tree.
