Now when you go back to your site you will see that you can enter more links (you don't have to recopy the html code or anything - it automatically updates on your site). Add in your new tutorial, etc. You can then go BACK into Linky Tools and change the date to yesterday if you don't want to your Enter Links Here button to show.
Using the INLINKZ tool is basically the same way. Now go pretty-up your pages!
