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.
Ok so 7pm for you is 8am for me (which is p early). If you can play at 9pm on Sunday, that's 10am Monday for me. If for some reason that day doesn't work, I have the next 5 days as well.
