Hi,
I have responded to Mario's reply to my comment on the online
documentation . As I expressed in that response I am happy to provide
help copy editing the English Translations. Unfortunately I can not
speak Spanish so I can not translate, although if online tools such as
Google Translate are used I could help converting blocks of text from
one language to another, copy edit the resulting text and provide these
drafts to gvSIG for verification. I must be missing something though as
I would expect that the "Whats New to Version 1.9" webpage would only
take a day or so to convert from Spanish to English. As I said, I have
not translated a document before so I am naive here regarding the
processes, but I have been using the automatic Google Translate facility
to read the above mentioned webpage and it seems reasonably accurate.
Apart from recreating the images using the English version of the GUI,
one would presume you could do a first draft of the text in several hours.
Cheers Simon
