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.
Let's get this nailed down. I'm busy this Sunday, and Saturday I have a few things going on as well (including another majors match). Next weekend would be preferable. Does that work for you?
I'm not available at that time on weekdays. From what you said I assumed you'd want to play on a Saturday or Sunday; this coming Saturday/Sunday (i.e. tomorrow and the day after) I'm probably too busy to play; would the next weekend work?
