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.
Bendiving I'm GMT +1 so I'm 6 hours ahead of you (it's 6:33am for me RN). I can do most evenings after 8, Mon during the day, or Sun morning all my time if any of those work for you
On Sunday I can do between 6am-midday which is midnight-6am for you, which fine if you want, but I also don't mind staying up late to play on an evening, what time do you usually come online on an evening (eg tonight)?
