[Posted 1:06 PM PDT, 02 May 2014] We are currently undergoing unscheduled maintenance on some of our primary systems. During this maintenance, various functions, including logins, may be unavailable. Please refrain from rezzing no-copy objects and making L$ transactions until the all clear is given.
Stay tuned for further updates and the grid will be back up online soon. In the mean time watch these cool videos that have been uploaded this week by the SL community.
