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.
Just for the record, I never actually scheduled a time with Alice Kazumi and just told him/her that I'd be available for challenge in PS. I have been on PS most of the time in some way, even if afk, and I haven't received any challenge requests. I don't know if I can call activity since we never actually scheduled a time and Alice Kazumi was actually the one who contacted me in the first place, but I'll be on PS most of the day today (might be out a little bit later for a few hours in the afternoon) to play if need be.
