I have one sentence for ALL of you: Get an agreement, even among you, and PUT IT IN WRITING. OK, you can videotape it if you prefer, but make a record of EXACTLY what you've agreed to. Also, if you work with others in the future, GET THAT IN WRITING. Yes, I'm what the English call a solicitor... a documentation lawyer. It's the job of the doc lawyer to cut the business of the courtroom guys. Even if you don't use a lawyer, just reducing agreements to black and white forces people to be express about their hopes and intentions.
