Elected moderator on Unix & Linux.
I've been using Linux since the late '90s and have gone through a variety of distributions. At one time or another, I've been a user of Mandrake, SuSe, openSuSe, Fedora, RedHat, Ubuntu, Mint, Linux Mint Debian Edition (basically Debian testing but more green) and, for the past few years, Arch.
My Linux expertise, such as it is, is mostly on manipulating text and regular expressions since that represents a large chunk of my daily work.
