@Kidong Song - try editing it now. If you can't edit it then create a new post and I will delete the original one. If your new post gets tagged as spam then you will probably need to create a new account. Unfortunately the bulletin board software seems to play up when somebody's first post is tagged as spam.
I know your e-mail domain is popular, I also don't know whether your post was automatically tagged as spam or flagged as spam by another moderator. I didn't put it in the spam queue. I'm just explaining to you some of the logic that goes into either automatic or manual spam detection.
The simplest way to avoid going to the spam queue when you announce your game is to contribute to the community with a few posts before you announce your game.
