I am Roberto Lapa, living in Florianópolis, Ilha de Santa Catarina, South of Brazil.
I have just subscribed to mobileread.com, after using it for years to clear up my doubts about Calibre and Calibre Companion, mainly.
I use (and love) Linux since its very beginning, way back in 1995
This site is a treasure trove of knowledge and I'd like to thank all of its members for their contribution, hoping I can give some of my own as well.
Also, a very special thank to Kovid Goyal for his wonderful software, without which I would not know my way in the internet maze of ebooks information (specially with their metadata misinformation).
