Once; voted F, but you should make the votes private so people don't know who voted for who. That should be another option when finishing up the poll.

EDIT:
Second option when submitting the poll.

Quote:

Make votes public: Displays all users who voted, and what choice they voted for.

I guess we could make a poll on if it should be public or private but I think it would eliminate people knowing or advertising their ride to win. Just less of a hassle IMO if the votes were private.
