What would be the best/simplest way to obtain this: when a user creates a topic in a specific category, the topic belongs to a specific user (e.g., @system). We already have auto-wiki, but this would be different.
I thought about using a wizard, but I did not explore yet how that would work. Especially because I would need an associated link to an external source, and last time I checked the Wizard was unable to do this and associated links seem to have no interface yet.
I can think of creating a plugin or using a webhook. I’ve never created a plugin so I don’t know how hard it would be, but I use a webhook for my forum that triggers a PHP script that makes an API request to Discourse. This is quite simple.
