To delete a Discord server, you need to have administrative privileges. Follow these steps:

1. Open Discord and go to the server you want to delete.
2. Click on the server name to open the drop-down menu.
3. Select "Server Settings" from the menu.
4. In the server settings, scroll to the bottom and click "Delete Server."
5. A new window will appear asking to enter the Server Name. Click on "Delete Server" again to confirm.

Deleting a server is permanent, and all associated data will be lost. So be sure to back up any important data before proceeding with the deletion.
