So what if it is an old thread. They may have something to add to it today, or perhaps they first noticed it today. Other people may just be checking out the thread and find some value in their new contribution. The thread police are everywhere...
The OP made one post in 2011 and vanished. I doubt he's going to be reading the sage wisdom being handed out. And I wasn't policing anyone; just pointing it out for those who might not want to waste their time responding to a person who has long since departed. And speaking of wasting one's time, see ya later.
