The course is very good at Sir jd, but it wont just be three hours a week if you want to get anything out of it, lots of time will be needed for you even just to get a very basic understanding. It would also help to have even just a basic understanding of HTML and CSS, if you havent alot of it will go straight over your head.
Building a basic site, amending text, adding pages, pics and uploading is easy and you will learn how to do it from the course, but only with alot of time reading and studying the notes which are mostly emailed to you from the tutor Gill. Very basic seo is covered I think. She will advise what books to buy and which sites to visit on CSS etc. Fireworks and photoshop will also be on your shopping list, the course in Jan uses cs5, but any recent version of it is ok, I have cs4.
Comparing some of the wysiwyg programs some have mentioned on here to dreamweaver is like comparing an old morris minor with a new bentley
Dont think your lad will be allowed on the course as its adult learning, but you can ask.
And give me a shout before you buy it
