Game & Event Hosts

People still seem to be confused how to register for comp games. I had a player today that has a well-known similar alt name. The avie she used at the game wasn’t the one in the drop-down menu so I esped her to be careful what avie she used to play… was that correct that they should always use the same avie to play comp games so that the scores are added properly? I submitted my winners and crossing fingers I did it all correctly. Just a question about adding only ten winners… is that because there wouldn’t be a chance to reach the top monthly winners circle if they had a low score one game? In other words, why don’t all scores count for anyone? (Pretend I’m in grade school)
