Thank you for your answers. I don't find any information about Joomla for Linux. I'll post the question in the French Joomla forum. There are other tools I need to work, such as Ranking Tool Box, Swishmax, Flash MX, Dreamweaver, Kompozer, and a few others... Instead of Adobe (Photoshop 7, Illustrator 10), I know I can use Gimp and Inskape for Linux, but : - it will take a long time to be able to work as fast with them as now with Adobe. - the question of ICC profile is very important for this work, and I have not tested Gimp and Inskape. In conclusion, I think I have to install Suse on a third hird drive (that means change my power supply), with wine, and try all these softwares without windows. Thanks a lot. (and sorry for my poor english)
