I know I've mentioned this website before, but here is a link to their site that discusses virtually everything that has been passed around regarding the events surrounding Sept. 11th.
What I like about this particular link is that they've put a red, yellow or green light next to each rumor... so that you can easily check to see if what you've just received (via email, etc.) is true or not. Feel free to pass this on to anyone who you think might be interested.
(There's a new email going around mentioning driving with your headlights on on Oct. 11.)
