The Penn State Athletic Ticket Office has just posted specific guidelines on how to buy, sell or forward single-game student tickets on their Student Central website:
More details are here:
The rules seem fairly sensible currently, for the most part. They say that these rules are subject to change before the online ticket exchange goes into effect on 25 August, but as of now my primary complaint is that to add a 2nd ticket to your ID card (for a non-student friend), you have to go to the BJC ticket office during very specific hours of operation and have them buy the ticket for you. I don't see why they couldn't make it so that if you tried to buy a 2nd ticket for a game online, it'd just charge you an additional $29 automatically for the non-student validation. Purchasing one additional ticket for a non-student is the only way you're allowed more than 1 ticket on your ID card (and the max is 2 tickets on your ID card, so only one non-student friend per ID at maximum).
Anyway, these rules do seem pretty reasonable, and should do a lot to combat the scalping problems of previous years.
