I voted. If you're registered to vote, you should, too. If you don't know your polling place, you can check here. If you think you are registered, but you don't appear on the voter rolls at your polling place, ask for a provisional ballot.
If you have trouble, don't let it slide! Make some noise:
National Campaign for Fair Elections; phone 1-866-OUR-VOTE (1-866-687-8683).
Register complaints about voting machine problems: 1-888-SAV-VOTE (1-888-728-8683).
Please don't sit this one out! It's your democracy too!
