... GrannyGeek, what does it mean, "registered Linux user..."
There is a Web site called The Linux Counter ( http://counter.li.org/
). As the Web site explains:
"The Linux Counter is started as a 'for fun' project to find out how many Linux users there are worldwide. The basic idea is for people to register themselves as being a Linux user. Of course, this way you won't get all Linux users counted as not every Linux user will register himself at the Linux Counter site.
Thus, the only way to 'know' the number of Linux users worldwide, is to make a guess, preferably a not-too-wild guess of the number of Linux users. Not making wild guesses there is only one way to go: statistics.
"So, the main purpose of the Linux Counter is to deal with statistics on all kinds of numbers related to Linux usage. It started with statistics on the number of Linux users and it extended to statistics on Linux users, the machines they use, software they use and in what part of the world Linux users are actually living."
It's mostly a fun thing, as obviously most Linux users have not "registered" with the site and many Linux users don't even know it exists. When you sign up, you get a number as a registered user. I like to use it in a signature because it gets the word "Linux" out there. Many computer users have never heard of Linux, or if they have, they don't know anyone who uses Linux. A few who see your sig will ask about Linux and this gives you an opportunity for a brief, non-pushy plug for our favorite operating system.
