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.
I'm GMT-4. I can play any time today, tomorrow morning until 2PM (my time) or after 9 PM my time, Wednesday between 1 PM and 6 PM my time or after 9 PM my time, Thursday any time except 6 PM-9 PM my time, Friday between 2 PM and 6 PM my time, Saturday is pretty rough so I'm not sure this early in the week whether I'll have availability; Sunday after 3 PM my time.
Looking forward to some fun, competitive games!
