Hi $pike,

If you figure this out, please let me know.  on August 5th, I requested a withdraw from Mt. Gox as well, and still have not seen any sign of my money.  I even went though all their hoops to establish a 'trusted' bank account.  For the first few weeks, whenever I would ask, they would tell me that they were having to do manual withdraws... although now, like you, they have stopped answering customer service requests completely.

My guess is that they are shifting from legit company to scam operation.  Trying to get as many people to send them money while putting a freeze on all real money withdraws (I've heard of some people still being able to get bitcoins out, but I have not heard of anyone able to get real currency out from them in the last 1 - 2 months.
