Thanks @axeman! I've a question. Could I participate with a picture that I've used before in some post? I haven't done that yet. But I'm planning to write some intresting articles that I'd like to complement with pictures. But, there are also photos that I could use in your contests, so I don't know if you neeed that exclusivity. Of course I wouldn't be a phote used in another competition, but in a post. Thank you very much!
