Recently had a need for some quick answers using SSI...google search provided this authors site. I was able to find my answer quickly and without difficulty use the material in my code.
The site was cleanly and clearly presented...no extra flash...no problems finding your way around. Just plain and simple, the information was right there.
Makes you wonder why we need all the fancy stuff we put up when you can find what you want without having to look for it...maybe more of us should try this too.
