This appendix contains the wire frames for the sample application. The wire frames do not represent all the screens of the GreaterCause site but sufficient enough to get a general feel of the user interface, associated fields, workflow, and navigation semantics. It incorporates various aspects of the information architecture as explained in Chapter 2. The navigation semantics associated with the wire frames are explained using the site flow in Appendix C. For pages with complex navigation, a side bar can be helpful for mapping the navigation elements of a page to the page numbers used in wire frames; you may also add callouts to navigation elements for improved readability.
