Not that the rapture is any laughing matter (should such an event come to pass, your beliefs are your own), but reading about this service made me laugh out loud last night.
"You've Been Left Behind gives you one last opportunity to reach your lost family and friends for Christ," reads the website, which is purportedly run "by Christians, for Christians." The domain name is registered through an anonymous proxy service, presumably to protect the proprietors from the Forces of Darkness, and not because they're up to anything shady.
I'm sure it's all legit. Just check out the verification mechanism.
The e-mails will be triggered when three of the site's five Christian staffers "scattered around the U.S." fail to log in for six days in a row — a system that incorporates a nice margin of safety, should two of the proprietors turn out to be unrepentant sinners or atheists.
See? Look at the redundancy they've built in.
