Handy and even fun, for US voters:
You put in your address, and it gives you a preview of the ballot you'll get on election day or when you vote early (which you should!).
You can click the boxes for your choices, then print or download a guide to take with you.
Really great for confusing ballot questions, judges you've never heard of, or in my case, navigating the 3 sets of university regents.
