We usually have 50 to 150 players online.  Our biggest day is generally Sunday, where we have 100 to 200 players active during prime time.  Sunday is our biggest day because of our new Sunday Tournament Schedule.  See our post in our subreddit for more information, including our "Cash 'em All" Promotion where you can win up to 1 Million Dogecoins for Free. 

We are developing a converter to make our hand history files compatible with Hold'em Manager and Poker Tracker.  We use Poker Mavens as our software, so any poker tools that work with Poker Mavens should work at PokerShibes.

We do not track the VPIP/PFR of the field.  It varies by gametype.  For example, I often see very loose players at the mid to high stakes Pot Limit Omaha games (200/400 to 2k/4k), but during tournaments like the Sunday Million (1 million dogecoin guaranteed), VPIP and PFR of the field are historically quite low.
