The Spanish user manual is already online
http://www.ribbonsoft.com/qcad/manual_r ... index.html
Why not include it for download as a zip file to substitute the English one?
By the way, there are some corrections that must be made prior to online dowload like paragraph 2.. it reads Licecia, it should read Licencia.
NOTE: Congrats to the translator team, this is a very good translation ;=)
