We have just launched a new photo submission contest site with a hemp/herb theme:
http://www.green-kingdom.com
Our auto-submission system is easy to use. Links back to your site are posted with your pics. Site visitors vote for their favourites and prizes are awarded for the top contris in 3 catagories (Gentlemen, Ladies and 2 or more).
Additionally, we are interested in trading hard links.
Take Care
