Zulip makes it possible to edit the content of your messages, letting you fix typos, clarify your thoughts, etc. You can also delete your messages if this is allowed in your organization. | Organization administrators can configure who can edit and delete messages, and set time limits for these actions. Administrators can delete other users' messages, but can never edit the content. | Editing a message to delete its content will cause the message to be displayed as (deleted). The original sender and timestamp of the message will still be displayed, and the original content of the message is still accessible via Zulip's edit history feature. This can be the best option for avoiding confusion if other users have already responded to your message.
