Sometimes a comment on a forum post really is a separate question and not related to the original question. Then you can break out comments and create your own post from it.
- Click on the menu for the comment.
- Select Own post.
- Select category and write a new heading for your new post. (Needs to be done also if you are going to archive the post.)
- Click Create new topic.
- Klick on click here to see the new post to see the new post.
- Now you can manage the comment as a completely separate post where you can e.g. archive, edit, assign, tag and of course reply!
