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 time? My Saturday is crazy, so I need a definite appointment. I'm GMT-5. Sunday is less crazy and I'm available them as well. Saturday about 11:30 AM is probably the best for Saturday, after 2 PM should be okay for Sunday.
That time won't work, I'm GMT-5 so that is the middle of the night for me! Since we are 10.5 hours apart, how about 9 AM Sunday for me, which is 7:30 PM Sunday for you?
