Chord Charts Galore! - iwillworship.com is a website that features chord charts of Christian music created by regular people using their music skill to determine the chords. Not every chord chart is spot-on correct, but it's free (although donations are accepted). For those just starting out playing guitar or bass guitar, it's a great resource to find chord charts for the music in your iTunes library. You can also request that a chord chart be created for a song. I'm not sure how good this feature is, but it's worth a try if you have the need. Peace.
