This is the Menu page. All of the other pages are connected to this one. You can come back here anytime by clicking the Menu button to the left. The Menu page usually shows who created the site and what kind of information it contains, much like the table of contents in a book.
Remember, you can take a break anytime. Just shut down the program and disconnect or close the phone connection. Then when you're ready, you can come back to this site and read the rest.
