If you want to save these instructions/tutorials for later use, and offline use, take these easy steps:
Click on the title of the post/tutorial you wish to copy. This will make the page that tutorial only.
On your browser (IE, don't know about the others), click on File>Save As>Web Archive, single file (or something similar) and Save. No need to change the name, unless you really want to.
That's it. Now when you want to work with it, just click on it. If for some reason it says something about connect, click work offline. Sometimes google ads or other active content that gets saved wants to search for it's missing pieces. This rarely will happen with my site, although using this technique on other pages might.
