BTC38 was going to implement Quark but volume was too large and they delayed the trading. When their system is ready for that volume they will add it. It's a great time to stock up on Quarks after the big crash of pretty much everything in december. Quark is one of my top 3 bets in the year to come.
volume to large?
I wish that was the case. But have you looked at the volume of quark at vircurex.com lately? It rarely is more than 10 BTC a day...
At the moment it's only at 2.7 BTC...
Georgem, yes, Vircurex does have low volume but they are just a small fish. Have a look here:

Quark is listed as having 102 BTC volume over the last day.
The only coins with a higher volume are Bitcoin, Litecoin and surprisingly, Dogecoin and Worldcoin.
