You can interact with your contractors through leaving comments and feedback on the discussion board, sending designers messages, and rating contest entries using our 5 star system.
We recommend using the public discussion board to provide more clarity to all the participants, and direct the contest as a whole based on the submissions so far.
If you have specific feedback to give on an entry, we suggest clicking on the entry and then providing feedback to the designer. This way it is kept private between you and the designer. Providing specific feedback to a design in the public discussion can sometimes turn off the designer from participating further for fear that his work may be copied. They want to feel like they have a leg up on the competition, and private feedback is the best way to bring it out.
