Many people will know how to do this, but some of as are not so experienced!
Should you ever would like to add something to the guestbook layout script, this could be one option!
As in my case, I liked to place a URL link on the bottom of my page so I can get quick to my password protected Guestbook Admin control!

To add this ore anything alls, find the file called
assembly.htm in your guestbook directory! There are a
more then one of this files you have to Check what themes you nominated in your Guestbook Admin control! In my case I used
chezpierre themes, and I found the file in this place
guestbook/templates/skins/chezpierre/assembly.htm I edit my
URL link into the file with
Front page, "Note Pad will also do" and saved it back on to my domain in the corresponding Directory! That's it the resold you can see in my Image above!
