I've had requests for the chords for my songs in here, several times. They've all been from people I was not only happy to help, but turned out even more to be people I was glad to meet.
The other day, I was accompanying someone on a song I actaully gave to them, on a CD. I was pretty familiar with the song, but had to follow along and watch some of the chord changes, because they were a surprise. I've also been pleasantly surprised a couple of times when people have performed a song I wrote, where they added a transitional chord I hadn't thought of.
There are worse things in life than being asked to give chords to a song.
