After reading the article, try to implement it yourself (hey, you might find you can do it, and it's how we learnt before the internet became a big thing), then *if* you get stuck post any specific questions you may have and we can help you move on.

You can't edit posts until you have a certain number of posts. This is an anti-spam measure. Do not post unnecessary messages just to get your post count up; we can spot this and it doesn't draw a positive response.
