a) Open Sprite named Layout. If you want to change the background, Replace the last Rectangle with desired shape of the same size. And delete all other object instead of Group Named Fields. Group named Fields contains four shapes to draw fields background area. Why? because email.swf loaded within swi is border less same to the files loaded in guestbook. If you need email.swf with borders email us and get it or modify the email.fla on your own risk.
