I'll post more extensively once I'm back on my computer (this comes from my iPhone), but the guys at Call to Auction were kind enough to read and answer a question I sent in. They also humored me with a nice little plug for this blog, so huge thanks to them. They're the leaders in the field, so I appreciate the effort.
I'll actually address my question (and their answer) in an upcoming, meatier post, but at least wanted to return the favor in some small way. Want to hear what I asked? Go check out their podcast! Episode 18 is the latest, as episode 19 was a one-off special that addressed 4.0.1.
