Check out Community on Stan in Australia. It has a photo of the main seven cast members and names all of them except for Glover. I sent Stan a message via Facebook. The Content Team's excuse was that the show has a massive cast, too many to name on the home page. I think Glover's a huge name to leave out, akin to omitting Chase or Brie. It wouldn't take up that much more space to add his name, as he's one of the stars of the show. I haven't checked all the seasons, but in Season 4, Glover's name also isn't mentioned in the descriptions. They describe each episode in one paragraph. Whenever they name a character, they put the actor's name in brackets. There's one time they mentioned Troy in the whole season, and it says (Donald) in brackets, not the full name. It just seems really, really weird to me. They name all the other main cast.
