I just logged onto an internet forum I hadn't visited in quite some time. I'd even forgotten my password. Anyway, I couldn't help but notice that it gave the option to stay logged on for anywhere (anywhen?) from 6 hours, up to (and I quote), "forever".

Cool.

So, you know, for me clicking "forever" was just an unexpected change of future address. For agnostics, though, it would be totally mind-blowing.
