Transfer BTC to bitfloor.com and then do ACH withdrawl for better rate. Or use fastcash4bitcoins.com where the rate isn't quite as good.
Bitfloor doesn't like my browser. I guess they don't want my business. It must be nice to be so successful that you can pick and choose your customers.
What browsing are your using? Works well in Firefox, but haven't tried in any others. I usually have 2 or 3 browser installations to use in case some site doesn't play nicely.
And Bitfloor was down for awhile yesterday and today.
