Example of Edit Form Page in the Portal
CONFIGURATION IN PORTAL PAGE SETTINGS
Top Section
Each Portal Page is given a Page Name. "Web" refers to the SharePoint Site. "List" refers to which list this page will work with.
Edit Page UI Settings
A page can have an icon or image. This needs to be a JPEG file 135px X 125px. It can be selected by using the Choose File and Upload Image buttons. Click "Hide" checkbox to not show an image or icon. A Page Title is required. A Page Description can also be added (which can be set to Hide so it does not show to the Portal end users).

Column Permissions, Column Validations, Lookup Settings, and Associated Items are configured here. See Advanced Column Settings for details.
Auto-fill User Information
This section determines how the user's information is filled in automatically on the form. See Auto-fill User Information for details.
