I understand your concern. And, I think that's fair. It would require cooperation and playing well together by all the group members- something any group of musicians should be able to do already!

I have the very same issue. I want to be able to share a songbook with a group of people who can all have immediate/shared access to an account. To be able to propose/vote/add/promote songs to a songbook and be able, when collected together for a (non-profit) confluence of a particul terRICfic instrument manufacturer, to share that songbook via a projector and a laptop connected to the internet. Music stands and pages are soooooo 1999....

I think Chordie would really benefit from being able to offer this service to users!
