Recipes - This is a very simple example that lets users share recipes.
Feedback - The Feedback forum is a fairly comprehensive system for allowing users to give feedback on an Internet site.
Mailing List - This is an example of how you can use NetForms to store data in an ascii file for importing into another application or database.
