I noticed that there was a terminator3 tage and a rise-of-the-machines. As they are the same film I tried to suggest rise-of-the-machines as a synonym of the terminator3 tag. However I received the following error:
Failed to propose synonym:
Version specific synonyms can only be created by moderators
I have no idea what that means, but it seems strange that I can't suggest a synonym, when it is clearly the same film.
Any explanation would be appreciated.
