I'm wondering now if when you wrote, "i dont know how to safe it" you meant you don't know how safe it is, or you don't know how to save the file.

To save HTML files that are open in a browser you need to go to the top of the browser where it says File and if you use Firefox select the option Save Page As and it'll open a save box where you select where you'd like to save the story. In Explorer it's similar. I'm not sure how Opera, Safari, or the google browser works though...But it should be in the same location.
