SMF supports the following emoticon-related features (note: emoticons are called "smileys" in SMF):
  * Custom smileys
  * Multiple smiley sets
  * Ability to re-order smileys
  * Popup "more smileys" window
  * Hidden smileys (users will not know they exist unless they type the code - especially good when you want to use two different smiley codes for the same image)
  * User-selectable smiley sets (users can choose which smiley set, if any, they wish to use)
