I have finished a translation into Spanish of the manual UserGuideNV http://wiki.lyx.org/uploads/LyX/LyXDevelDocumentation/UserGuideNV.lyx
The document es_UserGuide.lyx is available, and also the folder es_clipart, with some suitables insets for the Spanish version: http://home.tele2.es/ignacio_/lyx/ It's suitable for the Lyx version I have used, Lyx 1.4.3 (21/09/06) on Ubuntu-Linux. Thanks, LyX Team Regards Ignacio Garcia
