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.
Since my opponent has not made any effort at all to contact me, and has not responded to me, how are you going to decide who wins? Please don't say coin flips... I've been able to battle since the match ups were posted and i can not guarantee I will be able to battle in the follwing days. I have school and other shit that might pop up.
BlakBlastoise, Daniel already has decided to make advancement subjective, as to which user was more active and diligent in contacting the other. So that would mean you advance if the opponent doesn't respond.
