Hi, Tom - don't be taken aback. You'll find that we're very happy to help with chords. All ya gotta do is ask for chords on a specific song, and somebody will probably jump in and give you suggestions.
Dick Greenhaus, who posted above, is the curator of the Digital Tradition, so he's the guy who makes policy.
I don't really play an instrument, but I find that chords are helpful for fooling around with a song. I learned how to use ABCMUS to add chords to the DigiTrad tunes. It works very well.
