Leading article, January 2007. Rich research new year for everybody!

First, thank to the 21.530 visitors of the website in 2006, since its opening in march. 6.867 texts have been downloadable during these ten months. The year 2007 will be dedicated to finish the putting on line of the previous published texts, but especially to develop the headings are not documented: columns and proposals for cooperative research. The comments and the participation to the forums could be stimulated by these headings. Rich research new year for everybody!
