Hello!
Well, sometimes even if the Channel Manager is not an active Volunteer, could still be on Viki as a spectator, and used the account, if the Channel Manager don’t give you a reply in a few days, I think that you could contact an English Moderator and explain her/him what is happening so the English Moderator could add you to the team as an Norwegian subtitler. I’m not sure, but I think that you are referring to ‘’Seonam girls high school investigators.’’ The English Moderators seems active.
Maybe this information could be useful:
