Want to get a phone call from Michelle Obama? If so, get to work making a YouTube video explaining how you plan to participate in the national day of service on Martin Luther King Jr. Day.

Renew America Together, President-elect Barack Obama’s new community-service program, is sponsoring a video contest to promote the volunteer activities that will take place across the country on the January 19 holiday.

The winner will receive a call from Ms. Obama and the top three videos will be posted on USAService.org, a new Web site that allows people to post and find volunteer opportunities.

You will need to move fast. The deadline is 11:59 p.m. Eastern time tomorrow (January 15). Other details are available on the USAService.org site.

The Obamas plan to volunteer in the Washington metropolitan area on the King holiday, which takes place one day before the Inauguration, although the locations have not yet been announced.

The USAService.org blog has also invited guest bloggers to discuss their views on service through January 19, and several nonprofit leaders have weighed in, including representatives from Ashoka’s Youth Venture, New Global Citizenship, and YouthBuild USA.
