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.
I'm at GMT-4. Is a little later in the week good? Say either Friday at my 3/your 9 or Saturday at my noon you're 6? I'm decently flexible around those times if those exact ones don't work.
Sunday would be late in the afternoon into evening for me, like around 4/your 10. If you're ok playing that late, that's fine but if you'd rather play earlier I should be able to do 3/9 for you on Thurs. if that's better.
