Want to improve your vocabulary or just want to test how strong is your English vocabulary ? Here is a nice little way.
Just go to FreeRice and start playing. For every word there are four options. Choose the one which is the correct meaning of the word in the question. Besides you also donate 10 grains of rice to the UN every time you get a word correct. 
Just by playing everyday for about 5 mins you will end up donating a good amount of rice to those who need it.
So jump in and start improving the lives of many others !
Hehe, you visit Digit Forums?
I played for 5 mins and managed some 700 grains. 700 grains wont even be 200 grams. No way we can make kilos by playing for 5 mins.
Yeah, correct grams to grains and fix the first link.
@ Ashwin – Na… I got this thing in my office e-mail
By 5 mins I meant playing for 5 mins for a year. 
@ Harsh – Corrected.
Waste of time.
How can you tell that ? Did you try playing ?
Atleast you can help someone to some extent…
