Ok, its been said twice in the main post, once in the chat room, and once in a post in this thread. Maybe I just need to say it for yet another time.
The very, very, very first post in this thread says in big bold letters: Map submission deadline for Game Day XII is Friday May 16th @ 5:30 pm
I realize I forgot a timezone in that post, but a few posts down I clear up the matter by stating that it is EST 5:30 pm, which it is now 7:05 pm EST.
I am already working on uploading the maps and setting the rotation on the server.
Oh, and I had not updated the first post with the fixed Shmitz link until just now. So that should be working now also.
