100% agree @Canapin! I’m a big fan of the placeholder-forms component and I use it on all my personal and business Discourses, for documentation, creating Runbooks, and for semi-automating processes which aren’t ready for a Bash script.
I’d love to see articles in Documentation > Self-Hosting and #community-wiki:sysadmins use placeholders wherever there is some text/command to use which needs real-time customisation with user input.
