Useful plugin to minimise effects of “link rot”.

Amber is an open source tool for websites to provide their visitors persistent routes to information. It automatically preserves a snapshot of every page linked to on a website, giving visitors a fallback option if links become inaccessible.

Maybe combine with the Internet Archive? Ping to make a snapshot and point there as (another) fallback option?

Unfortunately, I can’t install plugins on a standard site…
