If people submit their post correctly, maps are wearing tags just above the screenshot of the content, like in the next screenshot is being shown. It can hold lots of info like for what game it is designed, what branch of the game, the modes, which status it is currently in, licensing information and the recommended amount of players.
The goal of those tags is that people don't have to put down a whole fairy-tail story about their map. Of course, it's still recommended to provide some more info than just that because that shows off you're even willing to put effort in the map by writing down information on it's content.
