From earlier today (since it's related, especially the HN comments): http://news.ycombinator.com/item?id=2612245
Personally, I would be wary of using any contract written by someone who isn't a lawyer. Telling people that you feel "there is no need to state the obvious as many contracts do" doesn't instil a lot of confidence either: how do you know what needs to be explicitly stated and what doesn't?
