Hi Paul. Currently there is a very collaborative song writing challenge called 50 90 where song writers attempt to write 50 songs in 90 days. The catch is that you don't have to write 50! Even if you just write one. It is a very supportative environment. They have loads of stuff going on all the time. Here is the link http://fiftyninety.fawmers.org
