Heads up! There will be a brief window of downtime tonight starting at
11:00 PM PDT and will last about 2 hours. Tonight's downtime should address the white screen and disappearing info box errors that we have seen the last couple of days. It is also setting up the framework for the upcoming Major tournaments.
Please be sure to save your games in progress before the downtime and clear your caches once we return.
Rumorsquash: Oakmont is not releasing tonight. You will be able to play Oakmont starting on June 1st. However, if you want to get a quick look you can check out the blog on my profile. =)
