We have a new release of our popular Master User plugin. This is a free plugin that allows Joomla site administrators to log into the front end of their sites as another registered user. The latest release (version 2.1.0) is now compatible with Joomla 3.2 as well as previous versions of Joomla 2.5 and 3.
The latest release also allows for greater security by allowing the selection of a separate master user group rather than restricting this facility only to administrators. This is to prevent the plugin from being exploited in 'brute force' password attacks. You can read more about the security issues here.
