Could function in different uses - you may want to rate your waiter's service, but not vote for them...
Plus, you guys are forgetting the vote preference (1-9) for non-mvte addresses can be set differently - e.g., "1 = good, 9 = bad". The "community" specifies the meaning.
Changing votes is hard, I'm lazy...maybe I just wanna ping freetrade w/ a bunch of 9's...
