Vaguely related note -- is there a way to confirm I sent BTC to the right address? I sent 15 BTC an hour or so ago and have 21 confirmations, but my balance @ MTG is what it was before I sent the coins. 
I have the same problem. 23 confirmations and no BTC on account.

In transaction info it shows "Not yet redeemed". Maybe its just some lag on mtgox?
