If you’re a “none,” non church goer, unbeliever, skeptic, agnostic, atheist, or somewhere in between, Atheist Alliance International is conducting an Atheist Census. It takes just a few minutes to stand up to be counted. Just surf here and you’re good to go.
Last I checked (a couple days ago), they had over 6,000 submissions. Cool. Not as cool is that since then, they’ve received a denial of service (DoS) attack. They’re working on the problem so keep clicking the link (or bookmark it) if you’d like to add your voice to the choir.
Good luck! (Here’s the link again.)
