Thanks to those involved in organizing the Linux Workshop in my workplace. The event was a success as things went on smoothly even though there have been few hiccups along the way.
I use Ubuntu 8.10 (Intrepid Ibex) to introduce Linux to the audience, and they were surprised to discover that it is easy to install GNU/Linux operating system on their laptop (thanks to Wubi), let alone using it.
As for the training manual, I use a subset of GNU FDL LPI 101 study guide manual which I found useful during the course of the workshop.
All in all, this event has renewed my faith in FOSS adoption in Malaysia as I saw people happily using GNU/Linux and free software during and after the workshop, without breaking a sweat.
