I gave the guide for Pages a bit of a spruce up and I have uploaded the latest version to this web site. It covers just about everything you may need to know. Pages is quite a good app and if Apple only allowed users to access DropBox for the sharing of files it would be even better.*
Please feel free to use this guide. All I ask is that you acknowledge usage and even link to my site. Much appreciated. The guide is accessible on each page among the iPad resources. It is also linked to the iPad workshop page and the resources page.
*Please see the comment below from Jonathan Wylie regarding opening up files in DropBox using the open in another app option. Excellent tip.
