You need two folders, one inside the other. Doesnt matter what the outside folder is called (maybe nagtuts), but the inside one got to be called nag. You got to extract the nag zip (the zip inside the zip) into this nag folder, and then just have my nags.html and logo in the outside one.
In this way you should be able to click on any link on the index page, and the tut will open....just like my page!!
