And the slogan?
"There's probably no God. So stop worrying and enjoy your life."
Not bad. I'm not a fan of the word "probably" (there's certainly no such uncertainty in religious advertising!) but I can understand why they've used it.
Anyway, the aim was to raise £5,500 for the cause (pledged to be matched by Richard Dawkins), and this goal was achieved just after 10am yesterday, the first day of the campaign. Current donations are just a touch under £60,000.
This is fantastic. It's an under-appreciated fact that for so many people, religion is an object of anxiety and distress rather than comfort.
A lot of people will find a lot of consolation in this message.
