So it's done! I've rebuild my site with Xoops since two month, and officially open it today! Some things are not finished yet, but the site is fonctionnal. Many thanks to the fabulous Xoops tool and to all developpers. I've searched since many month for a tools like this, wich allow me to build a big site with many downloads (more than 600) without knowing any word of php! I've dreaming about this, Xoops done it!
ps; sorry for my very bad english... I do what i can...
