Below are some links that I've looked through just recently and some of them seem really good. I hope they help g'snix.

http://www.writersdigest.com/contests/
http://www.firstwriter.com/competitions/
http://collectedstories.com/files/storyteller/contests.html

and here is a link to a forum for anyone suffering writers block. I thought it might be helpful.

I hope something in these helps someone. I'm actually in the middle of a creative streak but as usual, afraid that none of my stuff is what people want to hear but I shall keep attempting and hope something comes out of it. At least I can say that I've tried :o)
