The emoticons should be at the left of the post message box. Put your cursor where you want one to be and then click the one you want and it will insert the code in the spot which will bring up the smiley face when the message is posted! :wink:
Make sure that "smiles" are turned ON to the left of the posting box. If they are OFF then when you can turn them on this one time, or click on your profile and change your settings so they are on every time.
