Nuno you can write News article by yourself and then request moderators to publish it if you can't do it by yourself (I'm not sure about permissions regarding this).

In order to write a news article go to PGD home page. There just below advanced search and above "Community affiliations" section there is a dropdown list with a "GO" button besides it. Dropdown list defines which type of new content you want to create and "GO" button then takes you to the appropriate form.

You might also want to add some screenshots from latest demos that were made for Allegro.pas to increase the potential interest of other people for your article. First image in the article will be used as news article thumbnail. So don't use any smileys before actual images

If you encounter any problems please do report them.
