Wow this sucks, but was kinda expecting something to happen with RPM considering the rumors lately, the sudden pulling out of Poker Maximus, etc.
After a brief client update, I got the following message:
RPMPoker has been purchased by a third party. Your funds are safe and you will be playing poker shortly.
If you have another account on the Merge network, please advise email@example.com and we will have your RPM Poker balance moved there.
If not, please choose a Merge preferred partner and follow the steps outlined below:
See you at the tables!
See what happens when I take a month off? The skin has to close up shop!
I assume that you don't have to sign up a new account at those three particular skins -- it says they are preferred not mandatory. But I would also guess that the process of migrating might be smoother if you use one of those skins. From what I've researched, I think Hero would be a good choice.
That would suck for a lot of people if they don't honor VIP Points or Levels on your new skin. It would probably be wise to inquire which new skin might do this (for those with large points balances) and migrate there.
