Commenting on a "Resolved" or "Closed" ticket will set the status to "Reopened" it if the comment occurs within 5 days of the ticket being closed.
When commenting after 5 days, a "New" ticket will be created.
When a new ticket is created in this way, it will copy the basic properties of the ticket (including responsibility) but create it with the default status. In addition, this new ticket will contain the text of the associated feed item that initiated the update. The requestor will be notified when new tickets are created through this process.
