Weird, cryptsy just processed my doge sell order twice and now I have a negative balance of doge... short sells? lol
sort of, but beware, cryptsy had, for some users, automatically bought back the existing balance without notice, leaving the poor soul with a BTC debt. And if the price was above the "short" you'de lose some coins. Don't wait too long before buying back the coins, or tranfserring more dodge to cancel the negative balance.
