Your article might be in the process of getting approval, pending or rejected by the editors as these articles have to be checked by them so as to avoid any grammatical mistake or copied content in the subject content. If your article is of poor quality the editor will reply you and he will tell you what you are lacking in your particular article. So adequate time in needed by these people so that they will give their acceptance regarding your article as soon as possible. So I will advice at least to wait for 3 to 7 days for getting acceptance or whatever is the verdict of these editors. And lastly I would like to say that if you have any queries regarding your articles then you can contact - Webmaster.
