Ok, I'm embarrassed to even post this as I'm guessing I'm the only one that's never heard of this before, but what is a pin exchange?  One of the mom's on my mom board just got back and posted something about a pin exchange.  Then a few days later, my brother was talking about it with me.  I have absolutely no idea what they're talking about.  Could someone enlighten me?
