In "Contracts" there is a tab next to Milestones & Earnings that says Terms & Settings.
I did get a contract in place, though I didn't accept it before I was well underway with the project.
"And if it's a fixed-price contract, then do not submit work unless the first milestone has been funded."
You mean, if the money has been deposited into Escrow? Thank you, that was not a problem this time around (the client had done it) but I'll be sure to keep that in mind.
