Feeling gorged and self-indulgent after Thursday's food fest? Work off some of those calories by helping out in your community.

Between now and the end of the year, many local charities and other nonprofits ramp up their activities and need additional volunteers. Nonprofit staff, however, offer up one caveat: This time of year, volunteer generosity can sometimes exceed need, especially at small organizations. But even if you can't fill a spot right away, connecting with an organization now could lead to volunteering in the new year.

Here are some groups that need help. If none of these fulfill your do-gooder desires, look for part two of this story next week, when we'll run more holiday volunteer opportunities.
