The fee module is designed for one time use conference/event sites. It allows conference organizers to collect fees from registered users who signed up for the conference.
Now, the module has new features that allow conference organizers to print lists of confirmed (i.e. paid up) attendees. Several fields are exposed to views, such as the gross amount, the net amount, currency, and whether the user paid or not.
A filter is provided so that only paid up users are listed.
Because views works with nodes, the bio module is required in order to make users represented by nodes.
The module is used on the DrupalCon Barcelona 2007 web site.
