"As promised all subscribed accounts will start being Free to Play as of December 20, 2010.
On December 20, 2010 we gave all subscribed accounts 30 days added on, so they were not longer actually "paying" to have access to the Premium servers.
Well again today on January 13, we applied still more game time to subscribed accounts to allow them to be active into at least February 13.
Likely around the start of February we will again add game time to be sure no one has a lapse in game time!
We have lowered our Subscription prices to what we intend it to be for our Free to Play service, and if you want to play free starting now, make sure you have a subscription!
We plan on going Free to Play in early March, if you subscribe now you'll basically be getting about 1.5 months free subscription!"
It's starting at 7$ right now. Jump in on it if you'd like!
