What is a poker skin?
A poker skin is a group of poker rooms that share the same network. For example Battlefield Poker, Royal Card Club, Crazy Poker, Gaming Club, Betholdem, and many more are included in the Prima Poker skins. Players from all these poker rooms play in the same poker games. Most poker networks will allow you to sign up under all poker skins regardless of the number of poker rooms on the network you are already signed up for.
Can my spouse, brother, parent, roommate, sister, or anyone that shares my computer have an account at the same poker room as me?
Usually you are allowed, but they will need to get their own funding source for their account. Paying methods like Neteller or Firepay accounts can not be shared. You may however transfer them money at most poker rooms. If you don't follow the poker rooms rules you risk the poker room asking for your ID and then having your account frozen and funds confiscated.
