-While this started as a project to suit my own needs, since publishing the
-code a number of people have made some fantastic improvements and provided
-bug fixes and updates as the Django codebase has moved on and caused small
-portions of this application to break.
+As of February 2011, django-helpdesk supports custom fields on the Ticket 
+model. These fields are created by using the Django administration tool, and
+are shown on both the public and staff submission forms. 
 
-To these people, my sincere thanks:
+You can use most Django field types including text, integer, boolean, and list.

+The demo at http://demo.jutdahelpdesk.com contains an example of each type of 
+custom field, including a mix of mandatory and optional fields.
+
+Note that this feature is still in beta - it needs quite a bit of testing and 
+no doubt has bugs!
