Oh Flounder, there was an easier way to do this! As easy as 1,2,3!
Near the top of your page, next to "Gallery", is the "Visit" button. It provides you with the names of every Pet that shook your fins, and it loads them along the top of your page so you can visit them back. Just click on Visit then choose Guest Book and then "1 day" (or whatever period you want to see - I prefer "1 week" because not all of my friends can shake wings [paws] every day), Maximum of "1000" (so you don't miss anypet), Un-tick Show repeats and Shook their paws today
Now just click on the purple square with the maroon up arrow in it to put all of the Pets that shook your fins onto your tool bar! Simples!
