Hi
I am a German user and I speak fluently English, but I am not a native speaker, so please forgive my mistakes, when I write in this Wikipedia. In general, I rather comment in the talk section than really edit articles in English, since I know, that my English is not perfect.
About me: I am a (more or less) recent graduate in physics and electronics and specialized in nanofabrication.
