When you're chatting with a friend, you can send a graphic to show how you're feeling. These graphics are called "emoticons," because they enhance your words with emotions. For example, when you type this:

:)

you and the friend you are chatting with will see a small picture of smiling yellow face. Here is the complete list of emoticons you can send:

:) happy smile
:( frowning face
:P tongue out
:| straight look
:D big teeth
:x kissy face
;) winking smile
:> smug smile
:-/ confused smile
:o surprised smile
>:) devil smile
:)) laughing
:(( crying
X-( angry face

So put on a happy (or smug or angry) face and chat away!
