I actually talked to Dennis the other day for a while and caught up on things. Things are well for him, life has been busy and most (ALL) of his time is spent online playing poker and per him, rarely caught a live game.
His domain exprired some time back and it was then nabbed by someone else (a holding co. that buys up domains to resell them back to the market). I actually had a reserve on the domain but was lower on the list so didn't get it.
None the less, yes, PP is dead, Don and Dennis are alive and well. Don has caught several of my higher limit games and Dennis is doing well also.
