Welcome to MobileRead, John.
If you haven't seen it yet,
here is a page you might want to bookmark.......you can even download the users guide and "follow along".
The "contact us" button on the right will come in useful should you ever have any serious problems. Simply click, sign into your account, choose the "call me" option, and you will get called back almost immediately.
Hopefully, like most of us, you won't have any problems!
Enjoy the forums.
