How change sub-category (under Games/Video_Games)

Today, my site (http://easymemory.my-free-games.com/) is listed on your category :
http://dmoz.org/Games/Video_Games/Recreation/Browser_Based/Cards/Easy_Memory/

It's great to have my own category, but I don't think it is useful. I browse other categories and I think my site will be better in
http://dmoz.org/Games/Video_Games/Puzzle/Freeware/Memory/

Could you move it? And if you can, update the description:

Play online or download these free memory games (PC or Mac). Stand-alone or multiplayer free games (against kids, computer...). Try to reach online hall of fame.
Download or create your own memory games. More than 50 free games online.

There is an "Update URL" link at the top of every category where you can request the exact thing you are asking for. Hope this helps. Thanks.
