Link so you can catch up on the debate if you haven't.
My proposal:
Set a percentage that a GM is allowed to go above and beyond what the financial budget is set at by the team owner. Once we've decided yea or nay on that then we can proceed with determining what that percentage would be. I'd probably say 25%, but that can be argued over later.
I have set this to allow you to change your vote as well as I'm sure arguments will convince people to change minds on an hourly basis
