We have a newsletter made of links to curated external resources. I’d like to add a Discuss link next to each item, which would point to a corresponding topic in our Discourse instance so that the newsletter audience can click to comment and engage others.
I tried using the trick mentioned at Compose a new pre-filled topic via URL, i.e. using a link with
/new-topic?title=<url>, but this creates a new topic every time and this is not what I want.
I want the link to show the New Topic controller if the topic doesn’t exist yet, else take the visitor to the existing topic. Is there any way to achieve this with Discourse?
