On the hub for a game, under the tab that shows active servers, on each server currently you see the keys of all players logged onto the game. My suggestion is that instead of having that, there be a "Show Players" link on each server entry, that when clicked shows a drop-down list or something of all players.

They wouldn't be shown side by side but rather top to bottom. Byond members would be shown first, the reason its top to bottom is because byond members have icons they choose which appear to the left of their key, it would look nicer as a top to bottom list perhaps.
