You can test out our components from our demo servers.  We've created various logins for you to use with varying levels of restriction so you may see how the components operate from the view of each of the different stakeholders involved.  We have demo sites available for both Joomla 1.0.x and Joomla 1.5.x.  The logins are below.  Both sites refresh hourly to prevent abuse, and some features (such as com_users, com_massmail, and com_installer) have been disabled.

Reach out to us in our Support Center if you have any questions. Thanks and enjoy!
