In practice it takes the form of this blog which acts as a news feed for what's happening in the heart of the site; a central repository where we can find ways to help spread reason and goodness in the world, receive help from our fellow atheists and discover, record, create, discuss and improve the very best that atheism has to offer.
It has been said, with good reason, that organising atheists is like herding cats. Atheists tend to be independent minded and anti-dogmatic, yet that's not to say that we cannot benefit from belonging to a community of broadly like-minded individuals. We have a lot in common, even though those commonalities are rarely universally held to.
