Guys, it's not that difficult. All of the admins must be on TS or Vent, and each must know what their specific job is.
If you are the race steward, your job is the overall organization. You call SC and green flag (with binds mind you). You handle the server settings. You handle the decisions on whether to allow pitting or not. You handle on when the green is to be displayed (both by telling what lap it comes out, and actually flying the flag).
If you are a SC driver, you spend the day watching for idiots, crashes, and the like. When the Steward calls a SC, you spec the leader and decide the best course of action for picking up the field.
Ideally, there needs to be at least two other marshalls....one for watching to make sure people don't jump positions on during SC, and another to watch pit lane to make sure people don't pit during a SC until the field has come around behind the SC.
One more thing, if you set a rule about chatting (or whatever), you had better damn well throw the penalty at those that break the rule.
