I have been using
\LaTeX\on and off for maybe twelve or so years now, but in the past mostly via LyX. Recently, I have just started typesetting some articles and small booklets using LaTeX directly. My editor of choice is Emacs/AUCTeX, and I do all my work in Linux.
I have purchased a couple of Stefan's books, and that is how I learned about this community forum. Looks like there is plenty of activity here!
