We did this a few years back and just got flooded with too many questions. The most frustrating part was that Matt would answer a question and then we'd get the exact same question 10 more times the very next week. Also, Matt was a little uncomfortable giving out nutrition and training advice, since he could only talk about what worked for him and doesn't have a degree in nutrition or any personal trainer certification.
Here's the archive of the old Ask Matt section (this was back in the days that I was still correcting the capitalization of Matt's online signature, before he told me to stop doing that.
