Few days ago while visiting Firefox’s 500 million download celebration site i came across FreeRice, a very noble thought with a easy concept.
And for each correct answer you give, they will donate 20 grains of rice to United Nations World Food Program, to be distributed in poor countries.
Now this no-profit certainly shows the power of the web, with simplicity.
Go there and play this word game to increase your word-power instead of wasting time orkuting and sending forward mails.
note: i have also added their banner to my sidebar,if you can please link back to them.
