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.
Are you only free on evenings this weekend? Normally I prefer to play during weekdays....but I probably can do ~7-11 PM your time (I'm GMT-4, so that's 2-6 PM for me) on Saturday or 9-11 your time (4-6 PM my time) on Sunday.
In general I should be free some weekday evenings this week, however as I'm looking at flats to move to, I can't guarantee any one evening will be free until about midday that day - if you're happy with that I'm happy to pencil in tomorrow evening at 8pm my time, or otherwise I'm happy with 9pm my time on Saturday.
