Since I know we have some students on the forums, I'd like to makek sure they know about the essay contests that the Freedom From Religion Foundation. Yes, you can try to win scholarship funds for expressing your views on freethought issues
They have them for high school seniors, college students and "mature" students;)Next ones are in February 2011.
Check the rules, etc here: http://ffrf.org/outreach/student-essay-contests/
The FFRF publishs them in their newsletter, Freethought Today.
