What?? You approved this map? Come on, it breaks more than one rule. You give a bad example to other map-makers if they see something like that. In the future, you might hear someone saying "Oh look, that map has been approved though it lacks a preview image and author name. This means that even if some of the Map Submission Rules aren't followed, our maps will get approved!"
Is this something coming from Ralle? If it's so, I'll need to have a talk with him. If not, then I suggest you put the map back to pending.
