Lane, half the fun of working in Open tunings is figuring out the chords for yourself. It really isn't difficult to do, and you make lots of interesting discoveries along the way.If you have any specific questions regarding chords for songs in open C to which you cannot find any answers, feel free to PM me, or post them in this thread.
Open C is my favorite tuning, and IMHO the most versatile of all the open tunings.
