In its fourth year, You Don’t Know Mac is billed as the annual state-wide Mac trivia contest, but it is much more than that. Steve Welsh and his team have created a regional event that encourages involvement by all the Macintosh User Groups in Oregon, features celebrity guests and includes a MUG Leaders’ Summit. Steve talks about how YDKM is organized, announces this year’s guest host, how they involve both local and national vendors in the event, how the contest is organized and why he hopes it will inspire other MUGs to organize similar events.
