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.
Friday, Saturday or Sunday would be preferrable, I am GMT +1. So 5 hours ahead of you. How would your noon on Friday sound? Or if that doesn't work then noon on Saturday. Also is -4 Brazil? Because I recall that East coast americans are -5.
Unfortunately no, my sunday is really busy because I sheduled all my irl stuff for it sińce I sheduled all my showdown stuff for saturday. I will be avaliable today for most of the day so if you find any free time within the next 8 hours let me know.
