I will see what I can do with joomla. I hadn't though about it, it could be very useful.
Edit: I'm starting my SunVirtualbox and I'm gonna test the joomla stuff.
Edit2: I tested joomla. very good but there is way too much files for me and its a lot heavier that what I use now. My whole website is ~300kb and ~46kb compressed.
