7/26/2017 – Hi again – I’m looking to hopefully by the end of August begin redoing the site with a fresh look and new features, hopefully to be done sometime before the end of September. This includes a new design, appearance, scorekeeping (hopefully with live leaderboards) and more. Keep an eye out! Also I will be removing the Flash quizzes and geography quizzes that aren’t using Google Maps by then (remaking some of them after the remodel) to make the site more clean and organized.

      gonna try to start converting some of the challenge-type map quizzes before long.

    Any chance of adding time bonuses for number of cities and/or population cleared?

      There must always be the time pressure element that forces you into opting to clean some cities instead of others. Time bonuses would greatly diminish that effect… though starting with 20 minutes wouldn’t hurt. :)

        Agreed. 20 minutes would be great, as would a population data update, especially in the US (adding Chula Vista, increasing the populations of Las Vegas, Oklahoma City, Atlanta and NYC, etc.).
