what is PTS

I'm a newbie and trying to figure this place out. When I first started I saw a page about the point system, I looked over it and then moved on thinking I would find it again but I can't. I'm curious how the points are compiled or awarded and what PTS points are since I just got some. Am I now marked for deletion or retirement?

PTS was the separate board dedicated to political discussion, much like BTS. It has since been merged into ATS and thus does not exist anymore.

Well I tried to post just saying "Thank You" which I thought was polite and concise, but the post was unaccepted as to short and irrelevant so I will be a bit more verbose so that the person who took the time to answer me will know that I appreciate it. Even though this site is what it is, a little common courtesy is always in order.
