The Piper of Hameln

For written works, I believe most people here either just link to them on AO3 or else crosspost, so you can do that going forward. I can't speak for images. For my non-AO3 works (meta etc), I made a separate post for each and backdated it to the date I had originally posted it on tumblr. Of course, I only had a handful of things to post, so it wasn't a huge job.
