A 'software'? You can't hack into their
software (or so you'd hope), thank goodness. I seriously doubt you'll find any site that lets you create private games for play money. You're lucky if a site lets you create private games for real money. And if they do, it's typically a $5 minimum. And some site like Poker Stars
, you need to be of a certain status to create a game. FWIW, you can't create a game at Carbon, I just asked them a couple months ago, because I thought an Omaha HL tourney might be fun. An admin here can do it though. Oh, and welcome to Cardschat!
BTW, Carbon will let you create a ring game, just not a tournament.
