Could you add the GoxBTC/BTC markets as well of the bitcoinbuilder exchange.
+1. Also, I advocate replacing the Gox slot on the main page with the Bitcoinbuilder GOXCOIN-BTC pair instead ("Goxcoin" for now, probably, unless a major competitor arises doing the same thing as Bitcoinbuilder). The GoxBTC-USD pair should be buried in the Markets selection, IMO.
