I'd be up for help/collaborating etc, I am sure with the amount of people on here we could bang out a solid set of generic terms and conditions.
However, I am probably not the best guy to give legal advice lol. I need it myself haha.
But I am in a similar situation where I will need to write up some Terms and Conditions for my CMS as mentioned in a previous thread.
Anyhow, keep me updated and I too will do the same as and when I have something sorted etc.
