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.
Hi, we're opponents for the ORAS walkthrough tournament. I'm GMT -4. I can't play next Friday-Sunday, but I know we both need time to build teams, so how does Monday/Tuesday sound to you?
