Jim Wark has given up his post as publisher of the Richmond, Va.-based alt-weekly and intends to teach in Richmond's inner-city public schools. First, the 47-year-old will become a full-time student himself, returning to school to earn a teaching certificate and a master's in education. "I'd like to do as much good as I can with the 15 or so years of work I have left in me," Wark told the Richmond Times-Dispatch.
