It is no good just having a membership to another article site, in fact you probably already have memeberships at several other sites apart from your favourite one. You need to actually submit articles, too.
Break the ice. Write an article today for a site you have never written for before. You have to overcome the inertia of sticking only with the familiar. Remember, diversify to survive. Your income from article writing is only secure if it is from two, preferably three websites.
