Comments & Collaboration

Comments on Trello cards enable team members to communicate directly about specific tasks, providing updates, asking questions, and sharing context without cluttering external communication channels.

When to Use Card Comments

Card comments are ideal for:

• Providing status updates on task progress
• Asking questions or requesting clarification about specific tasks
• Sharing relevant files, links, or additional context
• Documenting decisions or changes made to the task
• Coordinating with team members assigned to the same card

Navigation to Card Comments

To access the comment feature, you first need to open a card from any Trello board. Comments are available within the card's detailed view where you can see all card information including description, checklists, attachments, and activity.

Adding Comments to Cards

1

From your Trello board, click on the card title you want to add a comment to. This will open the card's detail view where you can access all card features including comments, attachments, and activity history.

2

In the card's detail view, locate the Write a comment… button in the activity section. This button is typically found near the bottom of the card details, below any existing comments or activity entries.

3

Click directly in the comment text field to activate it for typing. The cursor will appear in the text area, indicating you can now start writing your comment.

4

Type your comment message in the active text field. Comments can include text, mentions of team members using @username, and basic formatting. Write clear, concise messages that provide valuable context or updates about the task.

5

After writing your comment, click the Save button to publish your comment. The comment will be immediately visible to all team members who have access to the card and will appear in the card's activity timeline.

6

If available, click the Show details button to expand the view and see more information about the card's activity, including timestamp details, edit history, and other team member interactions with your comment.

Comment Management Features

Once comments are added to cards, several management options become available:

• Edit comments: Click on your own comments to modify their content
• Delete comments: Remove comments you've posted if they're no longer relevant
• Reply to comments: Continue conversations by adding follow-up comments
• View activity timeline: See all comments in chronological order within the card's activity feed

Best Practices for Card Comments

• Be specific and actionable: Write comments that provide clear information or next steps
• Use mentions strategically: Tag specific team members when their input or action is required
• Include relevant context: Provide background information that helps team members understand the situation
• Keep discussions organized: Use comments for task-specific communication and external channels for broader discussions

Notifications and Updates

When you add comments to cards, relevant team members receive notifications through:

• Email notifications: Sent to card members and mentioned users
• In-app notifications: Visible in the Trello interface notification center
• Activity updates: Reflected in board activity feeds and card change logs

This comprehensive notification system ensures that important communication doesn't get lost and keeps all stakeholders informed about task developments.
