So there is this fairly new charity site called
FreeRice.com. It has English vocabulary questions on it. For each question you get right, they will donate 10 grains of rice to the United Nations World Food Program.
The other day I was able to donate over 3000 grains of rice on it. So have fun, build your vocab, help feed hungry people, and spread the word about the site! It's a nice site to keep open in another tab or window, and every few minutes or so while you're online, try to answer another vocab question.
And remember: Omphaloskepsis means navel-contemplation. ;)
