I think tonight will be the Earth hour at 8:30.
Correct me if I am wrong, it would be an hour of saving our earth by switching off gadgets and electricity. If you want to participate, get some rest of net surfing or watching TV, or pause on whatever you are doing later tonight at 8:30 and resume everything after an hour, it's like havin' the rotational blackout. :D HA! #whatamIsaying?
