You do realise none of the comments they get actually care about the map? (And apparently they're affiliated with the Yogscast....) Strange fans they have, although they as commentators are awesum.
Edit: Just read the comments, and funnily enough a lot of them are like PLAY RUGGED HORIZONS, haha. So some of them did actually care about the map and not just the people!
In all seriousness though, I mostly care about how interesting the commentators are, and (as bad as it's going to sound) how big their subscriber-base is and how much traffic they generate. The comments asking them to play other maps and do other things are obnoxious at best- wait
In the properties, make a byte tag and name it CustomNameVisible . 0 means it won't show from far away, but it will in short distance. 1 will show the name from far away. Then, create a string tag and name it CustomName . You can edit that into whatever name you wish to choose.
