Any question/discussion/blog/article in Tribe communities can have one topic or more. Any member can create or add topic to his/her content. Only community admins can edit/delete a topic.
When you add a new content (question, discussion, blog...), there will be an option to add topic(s). Click on the "Edit Topics" box on top-left corner of the question, and type down the topic you want to give to the question.
Our system will suggest a list of same or similar topics automatically. Click on the existing topic if applicable, or click on the "add new topic". The topic will be assigned to the content.
If a topic has not been created by anyone else, you can add it as a new topic.
When you create a new topic, it will be available for other users, and they can give that topic to their contents as well.
