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.
How early can you play? I sometimes stay up until 3 or 4 or 5 AM so I can play around 9-11 AM your time if you are available. Otherwise I don't mind trying to play around 6 PM your time on Thursday if possible.
