To whom may concern....I've just published my "MapServer Intro course" as a free service at my website. :-)
Unfortunately the course is available only in Portuguese but I'm already translating it to english .
To take a look check it out at http://www.webmapit.com.br/?lang=en and click "Services-> Learn2mapIt"
