I eventually want to move to a more structured collaboration tool for gathering content for programs. This is not something where there is a pre-existing standard. While the TWiT Network handles material over e-mail between hosts and Leo, programs we produce for the LISNews Netcast Network need something more than that.
One tool that intrigues me in my searching is Git. Such is a version control tool originated by Linus Torvalds. It may not be the best solution for what I am thinking of having. It is the closest to target that I have located, though.
