Hola Juan,
Thats it, we have a
wiki area. A few minutes ago, I finished the set up of everything, I also copied some documentation to the area, and setup permissions etc. for users. Next week I will re-arrange documentation tab, to eliminate duplicates.
I have to say that the wiki portlet is IN-CRE-DI-BLE

, is the first time I have used it, and was very easy, and very powerfull. With this tool will be much more easy to gestionate all documentation.
Thank you again for your suggestion, and feel free to participate.
Saludos, Jack.
