Something I did, that is really helpful is use the website ChangeDetection.com. What the website does is that you enter the URL for the TARR status and your email and anytime there is a change on that site, an email will be sent to your email stating there is a change.
My trademark application for example: I didn't like to constantly go to the USPTO site to check on the status so I signed up for the service (changedetection) and anytime there is a change, I get an email. The other day, I got an email saying there was a change, I went to the website and discovered that my application was now listed as being assigned to an examiner. It definitely saves time.
