FYI
I'm sure others have already found this, but for those that haven't clicked the "banding code" link right under BRDL at the top of the page, it might be worth checking out. Not only do they explain how banding codes work, but they provide a link to the list of codes that they use in the game.
BRDL uses these codes for solutions, but uses several bird code sources to help faciliate guessing.
Woo-hoo, the copied links work.?
