I ran up against the 1-confirmation bug, but it seems to have failed non-gracefully:
You must wait for 1 confirmation receipt of your submitted Bitcoins before asking a question. Please wait and try again.No error message. This is an error. Please contact site admin. ^_^
Heh, thanks for reporting it. It was mentioned in IRC also, and I fixed the issue. It wasn't anything to worry about actually. I simply forgot a final else statement near the very end of the script.
