Gypsy, I didn't want to confuse the issue with modes transposed! Naturally, you can start a Dorian scale on any one of the 12 notes of a chromatic scale.

I also didn't mention the hypo variants. Words like Hypo-Mixolydian are enough to scare away experts, as well as beginners.

BTW, M.Ted, the transposing chart, slide-rule or wheel has been mentioned a few times already in this thread. I agree that you don't need anything else for this job than the ability to write out 2 lists of 8 or 12 (chromatic version) letters.
