If you've got any legal questions about what to expect at your polling place, they're taking questions on their site now, and will publish a FAQ of the questions asked, on a state-by-state basis. So ask them if it's okay to write in "Anyone But Rob Black" on your District 6 ballot, or if it's okay to bang your Krissy Keefer taiko drum 103 feet away from the polling center -- they'll let you know!

Thanks for the tip, SFist Jackson!
