1 Introduction

The WAhelper project (http://www.freebsoft.org/wahelper) serves as a software tool for testing accessibility of Web sites. WAhelper consists of several components, two of them are:

WAchecker
Software library for automated checking accessibility problems of Web sites.
WAassistant
Web application for managing Web accessibility testing, including testing by humans and reviewing the problems reported by WAchecker.

WAusers is an assistive tool for managing multiple WAassistant installations. Its typical use is for providing public WAassistant services, when you need a global site user database with automated user registration and means for creating new WAassistant projects.

In a standard WAassistant project Roundup administrator creates new project, then logs in and defines its users, giving them project specific login names and passwords. If a WAassistant project is managed by WAusers instead, new projects are created using a Web application and WAassistant projects don't store users' passwords, WAassistant login names are mapped to WAusers login names for the purpose of authentication. So a single WAusers user uses the same password for all WAassistant projects he participates on.

Both WAusers and WAssistant are implemented on top of Roundup, a flexible issue tracking system, and their user interfaces are similar.
