It was a very difficult decision to establish the key language of this blog, in particular because English is not my mother tongue, but at the same time I am aware that it is the international language.
That is why, I decided to build it up as a multilingual blog. That means there is no one key communication language, but several communication languages. It will depend on the content of the article and to whom is adressed.
Are you ready to switch from one language to another?
