Howdy. As you've probably noticed, this is not SCP-3000. It's not an SCP at all. This is just a placeholder page to keep people from trying to post SCP-3000 before Series 4 is even available. We'll see if it works (odds are it won't, but ehn).
The contest for SCP-3000 will be announced soon enough, and if it's anything like previous contests, the winner will get the 3000 slot. Till then, go fill up Series 3.
[added:] And lo, here's the contest page. Good luck!
