As promised, I am finishing my first (private) publication in English. In this case, it is be the translation of my last book, "Niveles y Curvas con GIMP". Initially, it will be released as eBook through Amazon; a few days later, the paperback version should also be available at the editor's (CreateSpace) web page and then again in Amazon.
It will be interesting to see if the English version sells better than the Spanish one... so far, just a few units sold - but more than expected, anyway!
Oh, and I found some errors in the paperback version in Spanish. A few typos, some missing paragraphs... Simultaneous work with several programs (text editor, image editor, vector graphics...) has its issues, too. So I am preparing already a second edition.
