So, who am I? I seldom edit anything, since most articles have more knowledge than I do. From time to time, I run into something that I believe IMHO that I can improve or clarify.
I have been working with computers and been in the telecom area a lot of years. I have been working with standardization of some telecom areas. Eventually, I could edit something in this area, or in other areas where I have some random knowledge. In any case, the contributions I do are strictly personal.
And, as you might see, English is not my first language.
