If you have a Google account, check this out. this idea just occured to me about using Google (Blogspot) to share chord charts with each other by using Google Docs to publish chord charts :
just an idea for now but i hope it evolves into something useful. i think this method might work better than using a Wiki since each person can selectively share chord charts with certain Google users or with everyone.
for example, person A can create a chart and share it with person B & C and then person C can share it with person D, E, &F , etc. a good way to pass chord charts around maybe...
I don't think it's illegal to share my charts on a blog is it? It would be sad if it was.
