They are still around, although some long delayed payouts of late of maybe upwards of 3 months for some.
Yeah lock moved to the revo network, and then out on there own before crashing and burning .... granted they pretty much crashed and burned on the revo network and pretty much killed traffic on the network all together (although I hope to see the revo network like Intertops
rebound eventually, tops is a great site that now accepts all US players it seems although at one point was with invite only that changed).
Most US players frequent Bovada
and the WPN network skins now, so like ACR/BCP and the other bunch of skins, as well as betonline
and full flush
although some reports of long cashout delays on full flush these days as well.
Have only heard good things about Bovada and WPN though so would deff be my recommendations if you are looking at getting back into playing online. Bovada is anonymous tables while wpn is good to go with a hud if you have pt or hm without any additional addon 3rd party apps.
Should be some reviews on the pokersites here as well:
CC has a freeroll on full flush on monday nights if you sign up via their link, and for the freeroll club members there is a tuesday night and thursday night game (typically tuesday was BCP, thursday was ACR but you can play from either or now but not both at the same time.... so can play both from ACR if you wish for example). We also have a betonline freeroll on wednesday nights that any member of 15+ posts can sign up for.
Think that covers everything I can blurt out atm re the pokersites in the US.
