My end-of-post author box comes from the IndieWeb plugin for WordPress. It displays social icons for some links. For one reason or another, my Mastodon account icon was not showing on one of two sites. I edited the plugin files to make it work. While doing that, I noticed it supports icons for app.coracle.social links. Thus, I now have my NOSTR icon too. Scroll to the bottom of my newest article to see what it looks like.
