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.
weekends i usually work until 4 or 5 (which'd be 9 or 10 for you). if that's not too late for you, we could shoot for some time after then. sundays i tend to work more, so saturday at 6 my time (11 pm for you) would be a safe bet in case i work a bit late.
