Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
For the group "Let's Make a Game Together", you submitted an idea for a map. Criteria is added so you know where to focus on. You need to make your final submission before the First of June.
Good Luck with your map and hope you are enjoying the Social Group.

About your second question, if you read the OP carefully it said after the first tribute reaches a checkpoint, you may not move forward and all other tributes have 72 hours to reach the checkpoint.
How is today at around 5 pm my time (gmt -5)? I'm usually on #neverused if you gotta reach me. If that's not good I'm open to another time too (sorry for short notice, have been doin a paper)
