I play the Sunday free roll every so often. 450 players on average and probably 200 are AFK. I take a seat at NL as well and games are always running. If that's what you mean?
I've played on site on and off since last March. Had horrible March madness run was down to like $25 in the account and built it up to $400 playing .10/.25 & .25/.50. Very loose play (obviously at those limits) and not much traffic from what I remember. Just betting NFL there now but might start playing again.
