how do we create an article?

If you click on article which is on the bar above with home,wall and images on it e.g. when you have clicked on that you should see and blue box type thing where it should be like the one above this saying something like answered question. when that shows up on the top right hand corner of the thick blue line it should say create an article with a miniature plus sign next to it. click on that and then you should be able to make an article.
