the contest tends to provides that information? Read it, and if it doesn't say so, you can always ask right there. Usually it's done by pming the work in question to the person holding the contest...
When someone runs a contest on the site, they usually have all of the information in the first post! I suggest you go back to the contest thread and reread the first post. Usually, you post the link to your work in the contest thread so the judge(s) can evaluate it.
If that doesn't help, PM the person who started the contest and they'll help you out!
