Yep, I tried the withdrawal feature. But doesn't seem it works. I did receive the withdrawal request confirmation, but when I click it, it just shows your login page. When I log on, the withdrawal status doesn't change.

At first, I thought you didn't activate the withdrawing feature on this test mode, checking out the network log, it shows me an API 500 Internal Server Error. Turns out I'm requesting below the minimum required amount(<1mBtc). Maybe you could show a warning to the user if they requested below the minimum amount, I notice if I put 0, the site gives an error the amount not accepted.
