Mike Norton mentioned this awhile back (October 23, to be precise) and I've seen it mentioned a couple of times (most recently on Colleen Doran's blog) since then. There's a site that tests your vocabulary and every word you get right, they donate 10 grains of rice to feed the hungry. If you've been there before, give it another try, and if you haven't been yet, what are you waiting for? I just played for 1000 grains worth. Wouldn't it be nice if everybody reading this did the same?
