Choosing between nonprofits is kind of, well, weird, but Worldchanging has asked us to help them get the word out about the looming deadline for the Yahoo! Charity Badge Offering. "The charity represented by the top-producing badge as of December 31, 2006 will receive a matching gift from Yahoo!--up to $50,000." That's some serious dough, and it's not won by the number of dollars, but by the number of donors. (Not as snappy as "three days or three plays," but darn close.)

Here's what you do: Go to this link. Click on the donate button, and you know the rest. Good luck to Worldchanging!
