PMDG Tutorial

One of our PMDG-flying customers has mentioned an excellent tutorial flight which I'd love to try. Any ideas what/where it might be...??By the way, most of our customers who come and fly the full-motion B737NG simulator also fly the PMDG 737 on their PC at home. In fact, last Sunday, all of them did! Our instructor that day (who now flies B744 for Virgin, until recently B737-300/700 for easyJet) said he absolutely shocked how impressively everbody that day flew thew motion sim. A real testament to the quality of the PMDG simulation!
