Here is what all you replaymakers were waiting for, with help of Orko and guys from ORMO, opener challenge is coming back in full swing.
It will happen regularly every second month.
The rules, much like the premise, are also simple. You can't edit the replay before 440, you can't take other's work for your own, and you can change your submitted replay as much as you want before the deadline. But make sure you update your first post with it to avoid clogging up the thread.
