Yes, it works

I love this. Thank you so much!

For those with doubts: Yes, it does archive your existing posts after installation (see the FAQ). No, it isn’t perfect because the internet archive isn’t perfect. When we have a post we consider very important I check on archive.org a few days later, and re-add any missing media. This is more likely to happen with videos than images, I find.

It’s a real bonus to have automatic archiving on the one library anybody will check if they’re looking for extinct content. Worth installing Minor Edits, too, I find it works as advertised.
