Really need a wicked(or funny) grin smiley. btw, the indifferent smiley doesn't look like one. It looks like, shocked. 

I import all mine from another site. Take a look:

 I dont know if that such a great idea, i think their is a perfect amount of smileys to get the job done, too many smileys means overuse of smileys, which tends to tick most people off!

The last forum I frequented that had a large variety of smileys grew to have the problem of smiley spamming, the variety we have now is more than enough!
