The first 2015 semi-annual GeoNet contest is nearing completion with its end date on June 30, 2015. Prizes are being awarded to the top 10 members, and the standings are tight. I have extended the leaderboard to show the top 20 users since Esri staff will be excluded.
Want to get in on the action? The next semi-annual contest begins July 1, 2015 with the annual contest continuing through the end of the year.
