Script Summary: This script provide an easy interface for formatting comments, journals, signature etc in deviantART. You can format your text with Bold, Italic, Underline, Sub and Sup. Along with that, it has a easy "one-click" drop-down selection from all 500 emoticons.
Sharath(http://userscripts.org/scripts/show/12946): Original script is written for Orkut by this guy, I just added list of 500 emoticons(believe me, that wasn't easy!), added some new buttons and make it funtional in deviantART.com :-)
Currently, It is not working in "reply" section. If anyone have a fix for that, do let me know, I'll update the script.
