I know this is not a DIY link...but it does help your word power, and gives free rice to those less fortunate.
If you have some free time, want to improve your vocabulary for those sudden scrabble games, or to impress someone special. Try www.freerice.com
and feed some hungry children.
No loggin in necessary, and it feels great to help.
I just wonder who the lucky folks are counting all those grains of rice.
