(ESMILE) - Randomize your smiles
This power replaces any regular (smile) smilies that you post with another smiley that also has a smile. If you'd like to see a list all replacement smilies, click here.
If you want to use the regular (smile) smiley, you have to type it in uppercase, i.e. (SMILE).
If a smiley belonging to a power you do not have is chosen, then only the code will be displayed, not the actual smiley.
If you type multiple (smile) into one message, only the last smile will be replaced.
If you add text after a (smile), then the smiley will not be replaced. You can, however, add text before the (smile).
