Hey all,
I used to play a lot of guitar, but now I put most of my energy into coding a website called Communal Music Project. It's an online database of partially finished songs which you can download, add on to, and re-upload so others can do the same.
Super! Right? That's what I say.
Anyway, it's a lot of fun. Small community right now, but you all should definitely come check it out some time and give it a whirl. It'll be much more fun once there's a substantial amount of content on it, but it's still fun now.
