RaptureReady is a site devoted to getting ready for the end-times: this is from the FAQ:
How do you plan to maintain this site after the rapture?
I have no master plan for maintaining Rapture Ready all the way through the seven-year tribulation. After the big event takes place, I expect RR to last several months. After all, the internet was designed to survive a nuclear war. It should be able to survive the great catching up of all believers.
