Have fun, do good

I found this thing yesterday that's fun. It's a vocabulary game that donates a grain of rice to starving people for each correct answer. The rice is paid for by ads that are at the bottom that you don't even notice, and it's quite challenging. It assesses you at first and then starts you at whatever level is indicated. If you miss one you go back a level; 3 in a row and you go up. It is difficult, but the correct answers are shown and you always get another chance (or 7) and so you really do learn.

I am having trouble prying myself away.
