Emoticons are one of the many features of The 39 Clues Message Board. The feature was added a few months after the Message Board's beginning, December 13th 2012. Most are regular emoticons, 39 Clues based, or expressing opinions. These emoticons are available on many of the Message Boards. Emoticons also appeared on the Infinity Ring Message Board with more emoticons (mostly IR-related) and later, these emoticons were added to the T39C MB's library. Amusingly, the 39 Clues related emoticons remained on the IR MB. A number of cheese emoticons were added later to the IR MB for obvious IR-related reasons.
