One of these pages (the MDN Inbox) should just be deleted. I suppose that’s a sub-proposal here. The MDN Inbox was conceived as a way to accept unsolicited contributions. We never really got many, and never set up a reliable process for handling any contributions we did get.
That leaves 3 pages, 2 in the meta-docs and one in the glossary. I don’t think this is enough pages to justify implementing this as a macro.
We should decide whether we want to keep the big green button. IMO we should not, and should just use a link instead. But if we do want to keep the big green button, we could just use the HTML emitted by the macro (fixed so it works properly with the new narrower column width)?
Then: should I replace them with just a link (my preference , FWIW) or, more conservatively, replace them with the HTML the macro generates? Or a similar version that uses <button>, assuming I can do that?
