A comment can be added to any card within a Challenge Definition document. Comments can also be added for most individual rows within the cards of a Challenge Definition document. Comments can be useful for collaborating on your document, and you can choose if you would like comments to appear in your published document.
To add a comment or view comments for an entire card, open the card and click the comment bubble icon in the far top right corner of the card. The comment bubble will turn orange to signify that this is the row or card that you are commenting on. In addition to commenting on an entire card, comments can be made on individual rows within the card by clicking on the comment bubble on the right-hand side of the specific row.
When clicking on a comment bubble, the side menu on the left-hand side will automatically collapse to make room for the comment menu on the right-hand side. The user will be immediately prompted to add a comment when the comment menu is opened. Write your comment, and then click the save button to add it. You can also search for comments using the search box at the top, sort comments by date or sequence (i.e., the order of rows within the card), and show/hide archived comments at any time. Users can create one comment per card and one comment per row within a card.
Individual comments can be collapsed by clicking the 
symbol on that comment. Comments can also be edited, archived, or deleted by clicking on the appropriate icon on the right-hand side of the comment 
. Other users can add new comments or reply to your existing comments in a thread format to keep your comments neat and organized when collaborating.
When a comment has been resolved or is no longer relevant, users can archive or delete their comment threads. Archiving hides the comment but preserves the content (as opposed to deleting) in case you or others might need to refer to the information in the comment in the future. On the Preview card, users can elect to show or hide active or archived comments when publishing the document. While you might not want to show comments in your final document, it can be useful to show comments on a draft or in-progress document to share with others.
