@liaizon yes. That'd be editing history on lots of different servers. It's not a reasonable expectation.
But archiving stuff on your new server, so that you knew that your own stuff is backed up and available, would be a good next step.
Even better to archive on your own system that no one else can jeopardize:
@downey @liaizon yeeeeesssss @kensanata to the rescue!
I agree, it's good to have an archive out of band, but this is intended as a way for people to navigate your archive online.
