Habari gani! (That's Swahili for What's happening?)

If you are celebrating Kwanzaa, the word for today is Ujamaa, which means "Cooperative Economics." It's a day for thinking about ways in which people of African descent can pool their resources to strengthen their families and communities. It's also the fourth day of the week-long celebration, and I've been asked to do a roundup of photos and reports from the festivities so far.
