Greg Szczyerbak at Millersville University was kind enough to share an example of a Captivate tutorial he built to demonstrate an introduction to their
catalogue sorry, catalog ;-) Even more kindly, he said I could share it with you too. This one is a work in progress - he's having some students in the school's communication department work on the voiceovers - can you say "professional-sounding"? I like that idea, and I like how he's envisioning a whole suite of these tutorials, branding them as Compass Directionals. The link above is out of context; the landing page for the tutorial is here. Oh, and I see Greg's been busy, as now there are two more tutorials available.
