HI, I've just upgrade the editor of the website. When you want to writte a "noticia" or an article... Enter the Admin erea with the Password, then choose the icon noticias or articulos or Editorial ... Give the information asked in the boxes. For the text don't writte directly in the big spaces (firs for your native langage second for the English version) but open the icon on the right (a paper with a pencil)and you will get a popup to write your text with many tools availables. This editor accept flash, I will explain later why it can be useful.
I can now easily add PDF documents. As you can see on the left there is a new box called PDF for TWIOH.
When leaving the editor don't forget to save the popup and after save again berore you go back to the admin!
