I've herd this suggested a few times, and I'm just relaying it formally. The idea grew on me after a bit, what can I say... Make the commander opt-in/opt-out start in opt-out mode. So by default players aren't nominating themselves for command. Pros: emp_recruits won't accidentally get voted into command because they didn't know to turn it off. Cons: There might not be anyone to vote for the first few games after it's made the default.
