I figure "Kalmah" is not just one but multiple members of the band, because it would be easier than having 5 different users, so mabye they all log on as "Kalmah". Also mabye they they don't want people going Pekka, Pekka, Pekka, or Antti, Antti, Antti, when they see that they are on. All I know is that the way they talk is like they are one or more of the band members.
