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)
