FAQ
I have a livejournal/deadjournal/etc. Can I participate?
 Yes! In my haste to get this project off the ground, I decided that I would work on banners and templates in the months between the opening and the actual project. Journal users like this can hold up without responding to e-mail, journal comments, posting on their journal, or anywhere else online. There will be special templates for journals like this going up on the templates page soon. This way, your friends list will see it and know what you're doing. Just post the message right before you before you begin your day of silence.

I have a job and have to work, so I can't be silent offline. :(
 This is an online project. Yes, it is running the same day as the offline Day of Silence, but I also realized when I started this that maybe doing it online would be the only way some would be able to participate. I have at least two friends that were unable to take part this year because of work; if you are silent online and not offline, there's nothing wrong with that, just the same if you are silent offline and not online; you are delivering your message through silence, and that's what the project is about.

My school won't let me and my friends do this offline, what do I do?
There was a court case like this called Tinker vs Des Moines that set a standard that "students do not shed their constitutional rights when they enter the schoolhouse door." However, school districts still have a lot of power over what free speech students participate in. In Tinker vs Des Moines, the courts ruled that the First Amendment protected the right of the high school students to wear simple black armbands to protest the Vietnam War. It was known as "symbolic speech" and that the school district could only disallow it if they would properly show that it would cause a substanial disruption in the educational process. If you have asked a school authority figure for permission and they have denied you; go over their heads. I never bothered around with the principal in high school when I needed something serious; I went straight to the superintendant and once in my junior year, almost to the school board when I couldn't get a response from the superintendant. MY GSA wore special shirts, handed out cards when people would speak to us, and were silent; none of those things disrupted any of my classes, other than getting some odd looks from people and oh so lovely fake whispers calling me nasty names. Unless your school can prove your silence will disrupt classes, then do it.
