I have made a feature request recently in meta. You can find it at http://meta.askubuntu.com/questions/3203/how-about-page-numbers-on-the-top-of-pages-as-well . 

Do I just leave it there or are there any specific steps that I should do in order to get the feature request approved or rejected?

If I am to leave it there, then how does acceptance or rejection of a feature request work out in meta?
