This component makes it possible to add users to Joomla and Community Builder from the frontend. This is done by filling in a form and inserting the userdata directly in the database with mysql queries.  The component writes the directly to data user tables. This components also supports community builder but you need to switch it on in the components parameters after installing!   When you add a user the component checks for double usernames and for double emails if configured so.   All input fields have Javascript validation and an additional security check in php when sending the form in case javascript is turned off.   Add user frontend for Joomla 1.5 has multiple security measures to make sure that only Super Administrators and Administrators can add users from the frontend.   Add user frontend for Joomla 1.6/1.7/2.5 is more flexible because it operates under the Joomla 1.6/1.7/2.5 ACL system. This version also allows authors and above to add users. if you configure it like that. By default only Super users have acces. So be carefull with those ACL settings.   Features: Choose exactly which input fields you want to display in the backend parameters. Autogenerate usernames and passwords. Send notificationemails. Generate generic email addresses. Choose between Joomla user groups.
