I'm not sure who started it, and I hope whoever did will send me an email so I can give them credit.
There is a website, gratefulness.org where you can light candles for friends, or other people you want to remember. I believe a Court TV poster started a candle lighting group for Lana.
Click on an unlit candle in Lana's group and follow the directions. Lets keep those candles lit for her.
