i have offered a 21 day challenge the past 3 years on celebrations of light from Dec 1-Solstice. i am happy to do it again if people are interested. every day is a look into the worldwide celebrations of light during the waning of the sun before the solstice. the challenge is mostly to reflect on a tradition and how we are connected by these activities. https://www.kindspring.org/challenge/join/1990/
