Every Channel (TV or Movie page) on Viki has a section called the Community Wall at the bottom of the page. The Community Wall is updated by volunteers, specifically the Channel Manager or Moderators of the Channel*. They will often add information that would be helpful to viewers, such as broadcast schedule, number of episodes, cast members, subtitling status, and so on. The beautiful visual designs you see on some Community Walls are also created by volunteers.
