Well, i'm going to explain it a bit better:
The idea that i'm promoting, is, next friday 20, when london time is 5:00, that means, tea time, to turn off the lights of our houses since that time.
The world is divides in 24 pole-to-pole strips called Meridians. The "zero" one is the strip that passes by Greenwich, london. Since that, each country sets it's own time adding one hour per meridian at the east of greenwich, like Japan, and substracting at the west of Greenwich.
Argentina is at Greenwich Meridian Time (GMT) -3, so i have to turn off my house at 2:00.
Everyone who wants to participate, based on its info, needs to know wich meridan belongs the country you live on.
If you don't know how to start, yesterday i made this twitter, @aspergernetwork , wich is tied from arge media to bbc, deutsche welle and nhk. It has just one day and it has earned 20 followers.
You can use the Stop DSM pic there as you wish, edit it, copy it, spread it. I made it in GIMP, Gnu Image Manipulation Programme.
