I have taken the liberty of setting up a Google form to collect all this information to hopefully facilitate a seamless refund (and take as much workload off John as possible).
I am using this as the frontend for a spreadsheet to track refunds and transfers which will ultimately be used to generate a "sendmany" transaction that John should be able to execute in one command with bitcoind. We will of course check, double, and triple check the transaction when it comes to that point (or leave it to him if he chooses to go a different route) but I'm just trying to put some organization to this chaos in the interest of just putting this all behind us. (I should note that we aren't even sure we'll get a refund so all this may be for naught; but it's better than sitting on our hands).
I apologize to those who have already submitted this information in the thread but as you can imagine, it is pretty impossible to accurately track this stuff on more than 80 pages of forum posts (as well as use this information in a manner to streamline refunds). So please use this link for your refund / transfer information.
I realize that anonymity is of concern, so all fields are optional. It will of course degrade the usefulness of the spreadsheet if you omit fields, but it is ultimately up to you.
In the interest of full disclosure, I should mention that I will of course be sharing the information collected with John K at a minumum. Additionally, BigBenInLondon and / or ryepdx may be helping with the spreadsheet construction (though I think I have it mostly under control). There are some oddities with the amounts (and usernames) that will need to be hashed out; and I may need to enlist the help of one or both of them since I do have a life outside this forum.
Here is the form for refund / chip transfer tracking:https://docs.google.com/forms/d/1Db9Xx8NYvjnq-Pm7MmuVgWauTP1qSaFRyemI_sa5DkA/viewform
