Helmut has loved maps ever since he was a child, when he drew his own maps by hand for his personal edification (e.g. of the UK). Now his hands are a bit too shaky to draw these maps, but that’s where Google Maps and Places come in. These products, along with the hundreds of questions "ehg" answers in the forums weekly, keeps his day lively and interesting. Helmut is an active Top Contributor in the English, German and Spanish Maps and Places Help forums.

Jim's an engineer by training and inclination. A professional problem solver, with a mathematical bent. He's a data analyst by vocation and a Local SEO "by avocation" — as, he says, "both flow from the same problem solving bent, to extract meaning in a constrained environment largely as mental constructs based on observations."
