To respond to everyone that's been discussing the multiple accounts. This has been discussed in the past many times in this thread but I'll try to clarify it quickly and easily.

YES. You can use multiple accounts to bet with -- the limit is that you cannot self refer. YES they can all win prizes during competitions.

NO, you cannot CHAT with multiple accounts as that can lead to abuse of the tips that can be received in chat. We typically warn you first and then will mute if you continue to use multiple accounts to abuse chat.
