Here are some additional listings of writing contests that people have recently sent me:

• The Writers of the Future Contest (founded by L. Ron Hubbard in 1983 for SciFi and Speculative Fiction writers), and the Illustrators of the Future Contest.  Quarterly prizes plus a $5000 annual prize in both categories: http://www.writersofthefuture.com/contest

• Here is a Calendar showing grants and competitions  with due dates between August and September:   http://www.pw.org/submission_calendar/2010/8/all

Also, anyone interested in writing for children or young adults should seriously think of joinign the Society of Children’s Book Writers & Illustrators, aka, SCBWI:   http://www.scbwi.org

Although there are grants available to members, the primary focus is support and information, through newsletters, regional and national conferences, listings of regional critique groups, listing of online manuscript exchange opportunities, and a lot more.

Disclaimer:  I’m praising the SCBWI (it takes about six months to get the acronym straight) simply as a satisfied member.  The $75 annual fee is money very well spent IMO.

I suspect that a simple google search on “writing contest” will turn up a whole lot more, but I will post additional listings as people send them to me.
