Sorry, I saw your post an ap0calypse's profile, and as he is very busy, I'll just go ahead and reply by saying, that map was uploaded almost 2 years ago. This is not 2 years ago. This is now. It's becoming harder and harder to get maps approved. That map, nowadays would be rejected almost certainly.
Also, Description is important in a map, because it lets the user know what he is downloading. It can encourage people to download, and review your map.
Don't give ap0c hell, when you could be fixing your map. He rejected 3 of my (now pending) maps, and he's made me a HELL of a better mapper for it. He's doing you a favor inadvertently. Be happy, and look forward to updating your map.
Also, be happy that he even bothered to reject it, which he no longer has to do, as Ralle is creating a new map review system, and has told him that he no longer needs to review maps.
As soon as you update it should go back to pending.
