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.
Hey, I'm really sorry but something came up on my end. Would you be willing to reschedule for 6:30 PM instead? I can do another day or ask for an extension if you can't.
Actually, I think I can squeeze in 4:30 PM if it's not too late. Otherwise, I can do Saturday evening from 7:30 PM onwards or Sunday from 2 PM onwards.
