Smilies, or Emoticons, are small images which can be used to express a feeling using a short code, e.g. :) denotes happy, while :( denotes sad. The full list of emoticons can be seen in the posting form. Try not to overuse smilies, however, as they can quickly render a post unreadable and a moderator may edit them out or remove the post altogether. The board administrator may also have set a limit to the number of smilies you may use within a post.
