After I add a comment on a Trello card, I could not find the delete button. How do I delete comments from a Trello card?
Editing & Deleting
Edit or delete comments by clicking the "edit" or "delete" links beneath the comment. You can edit or delete any comment you make on any board. Board admins can delete comments made by any non admins on their boards. Deleting a comment is permanent.
Click "Edit" or "Delete" to edit or delete a comment.
