Which we shouldn't--AO3 is a great archive but nothing lasts forever. Everyone should archive in at least two places. I shudder to think of all of the fic that will be lost if Gossamer (the enormous, ancient, no-longer updating X-Files archive) goes down. Or the owner dies and quits paying for the domain.

Sorry for the OT. I've been obsessed with archiving since the loss of geocities.
