I got an email from them last night saying they'd look into it. It seems whatever Dwolla did with their Grid system messed up MtGoxs automation and they're a bit overwhlemed with all the transfered that got held up. All my past transfers with them have been quick and the MtGox guys seem really ontop of it just overwhelmed. Give them a few days to get back to your emails, mine took 36hrs to get back to me and I haven't heard back from a reply I sent them, but my advice would be just to have abit of patitence with them. This seems like an analomy and I'm confident they'll get my transfer and all the others that are held up worked out soon =)
