As title says: the in-game scoreboard should just list the map author. This is mostly to make the information more accessible - right now the only way to find map author is to look up the map in the vault. Doing so would allow players to give more feedback to the map authors, allow casters to more easily determine who made what map, and give the map authors a bit more recognition.
Apologies for the terrible edit. I'm sure it would look nicer than what I'm able to do in paint.
