I think this will be useful for the few of us who use emoticons or avatar for fun during commenting. Use it scarcely. Don't overdo it.
How to use: 1. Copy the one you want. 2. Place it in the comments or on any text field on dA. 3. Preview it to see if its the right one. 4. Post it!
It will take a while for you to go through all of it and with time will come to know of the ones you use a lot. So here is a preview of all the avatars used or listed, below. You can hover over it and see the name of the icon you want and just (Ctrl+F) find it on the list in the text file that you can download by clicking the button on the right. Have fun
