Great, thanks for the heads up. I don't know if i already have them or not, but if you give joesmoe @ github access to your github, i'll update the ReadMe some to help avoid some of these questions. I'm no programmer, but i can certainly pitch in for the documentation effort!
Would be good to have in the Readme. There are hints to this when reading through the original ATP and this ATP post that MtGox is the only usable exchange with the ATP as it currently stands due to making market orders. Certainly it is not as clear as it should be.
