We need to build that, anyway, so that we can give people the opportunity to move their content from 30023 Markdown articles to 30041 Asciidoc articles.

That way, they can write in whichever markup they prefer and then "upgrade" or leave it, as is.

Moving from 30818 Markdown to 30818 Asciidoc is even easier. Just have to copy-paste the fields into a new event or set of events, and have them sign it.
