Earlier in the week, an old friend alerted to me to a musician community called MacJams.
18,000 musicians are currently members. The purpose of MacJams is to allow musicians to upload their material and to share and comment on each others material.
I've uploaded 6 tracks so far:-
Using a Creative Commons Licence, contributers keep the copyright to their work but can legally upload and share this with anyone who has internet access. This is simply brilliant and I wish I had known about this before.
Since I'm already in contact with people at Creative Commons in other areas (science), and will certainly be mentioning MacJams. I hope that as word spreads, by this time next year, the number of members at MacJams will have risen dramatically.
