Update for those who, like me, were not in the ACH verification queue when this stuff went down:

I thought that it was impossible to enter the queue because the website refused to let me upload photos, even though the ones I was trying to upload were less than 2MB (the filesize limit specified on the site). But this morning, after seeing a tweet from @bitfloor, I tried again with a file size closer to 500K and it worked fine. Hopefully in a week or two I will be verified and will then attempt an ACH withdrawal. I have revised my estimate of the probability that I will get my USD back slightly upwards.
