@DrOct @odd You can put it anywhere. If you want a visible link, you can have it in the content, menu, footer, etc. on the page you're linking to from Mastodon. If you don't want a visible link to Mastodon on that page, you can add it as a link element in the head. You can use the curiously named Meta tags plug-in for that (it should really be called the Head plug-in).
