When a ticket moves from Teamwork Desk to Teamwork Project you may notice that a task or sub-task is assigned to you in Teamwork Project. At this point, you can leave all of your project notes in Teamwork Project. There is no need to update the ticket in Teamwork Desk. But in addition to adding your note, when the task is fully completed, you will need to log your time and then mark the task as complete. Do not check the billable box unless you are a developer intending to bill for your time through Teamwork Project.
If you are pasting any images, you will notice that the images appear as attachments below, and unless named will all have the same generic image name. There does not appear to be a way to edit the image names once they are created.
