If you've been using it for a couple of years, it isn't mine. I only did mine about a year ago for my own use and only put it on my web site recently to help out a friend.
It's easy enough to do so I imagine lot's of people have done it.
BTW Mine sites are not that widespread. The recently released DNB NASA light pollution map
http://apod.nasa.gov/apod/image/1212....3600x1800.jpg
imaged hundreds of bush fires all over central Australia that some people have been attributing to mine sites.
The map had bright spots all over the Great Sandy Desert where there are no mines, just beautiful dark skies. The bright spots were brighter than cities like Sydney. This is because the images were made with ISS Visible Infrared Imaging Radiometer Suite cameras so the fires came up particularly bright.
