I've been using LaTeX since I started university 6 years ago, and grateful to everyone ever involved in the kernel, or in the various packages, distributions and websites, those who introduced me to it and those who answer related questions!
I'm following with interest the developments on LaTeX3 and also the alternative engines, which I hope to one-day be able to exploit more!
