Watchers can be referred to the Designhill users, especially the designers who have subscribed to 'watch' what's happening on the Designhill platform.
Designers usually leverage this tool (watch) to keep up with the contests that interest them.
Any registered user can watch a contest — please make a note of it.
Watching a contest enables you to receive notifications, similar to what the designers participating in the contests get. In simple words, this tool is the best way to stay updated on what's happening in a running contest.
Please be reminded that you can only see the number of watchers and not the watching user. But if you post a public announcement in your contest's message section, watchers and all the participants will get notified simultaneously.
