'Smilies' are small graphical images that can be used to convey an emotion or feeling. If you have used email or internet chat, you are likely familiar with the smilie concept. Certain standard strings are automatically converted into smilies. Try twisting your head on one side if you do not get smilies; using a bit of imagination should reveal a face of some description.

Here's the list of currently accepted smilies:
