Well, here's my first attempt at the rulebook. I feel like it's a little disjointed, and could stand to be reorganized a bit, but the main ideas are in place. For those who don't want to read the whole thing, here are the highlights:
1. Code of Conduct. Basically, these are a few guidelines for clean passing and a requirement (inspired by another forza ruleset I saw) that no driver take a position due to contact he/she was part of. In other words, all passes must be clean. We were doing really well at this when the Clio Cup started, but it's fallen off in recent weeks.
2. Race Stewards. I expect this system to be imperfect, but it's a first effort. Basically, the host (one member of the Rules Committee) acts as a race steward. (Or, if a committee member wants to watch over the race and there's an open slot in the room, that's OK too, but I wouldn't want to do it, so I'm not willing to ask anyone else to.) And lest anyone worry that I'm going all "Big Brother" about this, the qualifications for being on the rules committee basically consist of wanting to be on the rules committee. We're pretty good around here about self-governing, so I don't really see any reason to change that.
3. Qualification races. Qualifying races are run for 10 laps with collisions off. Basically, most consistent car wins the pole (finishing order). Qualification races are currently going to be unscored. I'm open to change on that, though.
4. Scoring table. I laid out a new scoring table based on the lobby points system. It's probably also pretty similar to the 10-lap Clio races.
Edit: I added a flag system and a "one-move" blocking rule.
Anyway, I'd love to get some feedback. The full document is attached.
