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.
Both days are cool. I would prefer if we could play next week so either on the 9th or the 11th but we can keep this Sunday 4th as an option. We can decide on a specific time later.
wanna suggest a day when you want to play so we wont drag this forever? next week sounds good enough unless you have exams next week and wanna play a bit later.
sunday like 10pm your time seems okayish but just in case another time during next week would be a good alternative so let me know your suggestion for next week (day and a specific time)
