I have a small question regarding how billing works. I have a team of ~10 devs and I want to start introducing Graphite, but I know for a fact that not all of them will want to jump right into it and change their workflow until they've seen it from others and understand how it works.
Can I send invites to parts of the team as they want access or is the billing based on how many github contributors Graphite sees from PRs in Github like so many other developer tools that connect to my Github account?
