This doesn't work.

[*]Bids can be canceled by typing itemcode cancel without quotes in a subsequent post before the last 48 hours of the auction, but should not be done after. (It'll take one more update for the cancel to go through, because posts are processed sequentially)
Have to wait for one more post after yours, cancels don't go through immediately unfortunately. (If you had pressed Update right after posting Post #102 without editing Post #14 you would've seen it work)
For it to work immediately I'd have to create another loop to read and process all posts once more, which isn't quite as simple as it sounds. It's on my to-do list but it's not there yet, I'm working on proxy bids first.
