We have taken the Portal submit feature off-line. It will likely remain that way until late Thursday or early Friday. You will still be able to play games on the site until the time it goes down. I will probably put up a non-database-driven page to play Domo-Kun or something while the database is down later today.
I hope everyone is as excited as we are! This is the biggest server upgrade in the history of NG. Site performance is EXPECTED to improve anywhere from 150-200%... We are hoping it will be in the 200% range. :)
