A lot of teams have been using ticket comments extensively to collaborate everyday. Notification Center further improved this experience by bringing real-time updates. 

As we continue to build more improvements to this experience, we've shipped a small-yet-important one today: edit & delete ticket comments . 

You'll find both these options right next to the comment you made. 

By default, comment authors can edit their comments while administrators can edit all comments. Likewise, comment authors can delete their comments while administrators can delete any comment. 

You can customize this using profiles as well. Just allow the 'Modify Comment' permission for a particular profile and all users under that profile will be able to edit & delete comments. 

In addition to this, you can also check out each comment's revision history. 

As always, feel free to respond below and let us know what you think. If you have any ideas on how to improve collaboration within your customer service team, we'd love to hear those too!
