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.
What's your GMT? I'm GMT -3, and I'll be available to play at 19:00 pm. But, if you want to battle earlier, I can battle at 13:00 pm (except on thurdays and tuesdays, maybe fridays too).
