I included a parts list with a note at the bottom about the LED orientation. But I didn't note anything else. Then Stan posted above about all the other things so I didn't add those to the list. I will do that for the next batch of kits. I was going to try and fix the PCBs as you described above, but they went so fast I ordered more before trying to make the adjustment.
My color printer shot craps or I would include one of Stan's detailed pictures on the list. All I have at the moment is a B/W laser printer. Guess I'll try it with that and see how it looks. Probably not too good, won't show the pretty red boards... I was looking at some color lasers, but haven't found one that doesn't need $300-$400 worth of toner when it runs out. Nearly double the cost of a 'home sized' printer! Maybe ink jets weren't so bad?
