At the bottom of the main contest page there’s a comment area that is viewable by everyone.

This comment area should be used for general comments about the contest - anything that is to be communicated to everyone participating in and/or watching the contest.

Private comments and/or feedback can also be left for individual designers in two ways:

-Click the chat bubble icon beneath an entry on the contest.

A comment box will appear where you can leave a comment that on that designer will be able to see.

• On the fullscreen view of the entry, there’s a comment box that allows the contest holder to communicate with the designer directly as well as view any comments the designer may have left.
