Developing a project like BLOOD WAR ( Bucket Loads of Old Dice WAR - a retro-clone of Warhammer) is a minefield of misunderstandings and potential conflict.
Do we, as the authors want to financially gain from our hard work?
Do we want other people to be able to financially gain from our hard work?
I don't know the answers, but unless we're all clear on where we stand with it then there will be trouble ahead.

I think it's the right way forward and I hope all contributing editors / authors can agree to it as a legal framework, we can stick the icon on the blog, forget about it and get on with the gaming!
But if anyone reading that license has any questions, queries or concerns then drop a comment. I've no intention of trying to railroad this through.
I should also note that I have had personal correspondence suggesting the OGL might be a good framework so check-out OSRIC and it's license to give an idea of how that works too.
BTW, none of this provides us with legal protection against claims of infringement of other companies copyrights, it's just about making it clear what people can do with the things we post here.
