Home Power #30 • August / September 1992 3 From us to YOU People Home Power Magazine’s Fifth Anniversary: growing, graying, Stan Barr helping, and paying Barry Brown Stuart Caruk Growing Sam Coleman As you may have noticed, Home Power Magazine has been growing. Growing is a natural process that is energy, ecstasy, and exasperation combined. Bart Diaz Scott Ely Graying Chris Greacen Home Power is now five years old and still growing. While growing is fun, it is also Kathleen Jarschke-Schultze scary. Over the last five years, the amount of grey on our heads has definitely Kid's Corner Kids grown. We all pay a price. For Richard and I, the price was becoming too high. We needed HELP! So that’s just what we did, we hired more help. BUT—and there’s Chrissy Leonard always a but—more help meant more mouths to feed. Dan Lepinski Bradley E. O'Mara In the beginning of Home Power, everyone’s labor was donated. No one received a John Mills paycheck. Five years down the road, Home Power has taken over the lives of all Therese Peffer those involved with it. Home Power must support the people who produce it. Mark Peterson Helping Karen Perez We welcome Therese Peffer and Chris Greacen to the Home Power Crew. They Richard Perez work, with Richard, Kathleen, and I, on Home Power—writing, editing, illustrating, Shari Prange processing the mail, and other chores on an endless list. Richard Rahders Paying Al Rutan We have decided to raise Home Power’s subscription rate from $10 to $15 per Mick Sagrillo year. This increase allows Home Power to grow without Richard and I burning out Bob-O Schultze or having nervous breakdowns. This increase allows us to support full time help in John Takes producing this magazine. Everyone who works here could easily be making twice Michael Welch the bucks, in half the time, anywhere else. John Wiles More Growing So what will you get for your extra five bucks?
