I'm up for it, but instead of posting to forum, would a semi-open source control system work? Everyone could just upload what they wanted under their username. Or even shared ftp server.
That is actually a great idea. I think we should at least encourage people to attach their code to their post.
The reason is to show other people how we come around different problems. For instance, I had a hard time with particles

My thinking is why? You could just use an existing service like code.google, sourceforge, etc. etc.
That just seems like a lot of work and registering for sharing code. I think it should be easier to do, so more people will.
