I would like to “choose optional tags” for my topics. When I type a word like “question”, an existing tag appears. When I type “documentation” or “tag”, a message “no matches found” appears.
How can I add a new tag to my Discourse topic?
Is it perhaps limited to users with a certain Discourse trust score?
Yep. You currently need a trust score of 2 (or more). The default is 3, I lowered it to 2. Maybe 1 would be fine too. I’ll see it to 1 and see what happens.
Edit: Done. And you seem to already be a “basic” user (= trust level 1), so you should be able to make new tags now.
