What should the next U.S. president do on his first day in office? Make a pledge to eradicate nuclear weapons? Build more bike lanes? Create a national sales tax and eliminate all other federal taxes?

A Web site, On Day One, is asking Americans to make their suggestions for what the next resident of the White House should commit to. The Internet project is run by the Better World Fund, an advocacy group in Washington that seeks to improve U.S. relations with the United Nations.

Aside from ideas from everyday people, the Web site includes video interviews with politicians and other well-known figures. Walter Mondale, the Democratic presidential nominee in 1984, says that the next president on his first day should promise to build better relations with other nations, while Gov. Christine Gregoire, a Democrat from Washington, wants the new commander-in-chief to pull troops out of Iraq.

What do you think the next president should do on his first day?
