It's been about 10 seasons since I played, and I was thinking of joining. When I last played potential had just been introduced and the FSS was new. Anything new and exciting about  the game going on?

I started playing HD about a year ago, and wasn't around when potential and FSS were implemented. Therefore, I can't really comment on many of the "new" things. But, from what I understand there hasn't been a really big release or update to the game since potential was introduced. There have been several mini-updates of late...including a change to postseason selection criteria, color coding of potential in different areas of the game, and an added "bracketology" sort of page. 

The game is incredibly enjoyable for me though (and many others), and a great community has been established in many worlds (especially Wooden!). You should give the game a try again!
