OK, here is one that might be easier. It will give a drop down menu with smileys.....no need for adding anything to the cencored words list.
This will add a drop down menu to the left of the text box listing your smilies with a preview box below it. There is also an option to 'view all' smilies which will open a pop-up window containing all of your smilies...
All you have to do is edit the red part with the full url of your smileys....
Put this in your Global Footer.
