On September 10, 2002 we started a sort of a WTC memorial on NYCfoto.com, asking people to light candles in memory.
Every year on September 11 we replace our website with candle memorial, asking visitors to "light a candle". We invite everyone to visit NYCfoto and pay their tribute: http://www.nycfoto.com
