Hello @GustavoMarques ,
Welcome to the Community! Please let me know what exactly are you trying to achieve and I will help you out.(most members come here to ask technical questions on Infineon products, or to help answering them).
You mentioned 'article' - that usually mean tech blogs or knowledge articles in our community, which are currently published only by Infineon employees. Is that what you were trying to do? Do you have a topic that you would like to share with our community?
To get more clarity, it would be helpful if you could share from which page you tried to create an article, as well.
