In Joomla 2.5 and above, users need to register with a unique email address. Joomla prevents registration using an existing email address.

This is not ideal for example where club members are children and they should be registered with a parent's address. It also makes creating test users more difficult as they all need to have separate addresses.

This system plugin allows administrators of Joomla sites to enable users to register more than one account with the same email address. It works by overriding a core class to disable the duplicate email check.

The plugin also uses the Joomla Update feature to check for new versions and enable simple updates when new Joomla versions are released

This plugin is based on the users same email plugin - (C) If you are using that plugin then it must be removed before installing this plugin as they both try to override the same core class.

Currently supported Joomla versions: 2.5, 3.3, 3.4, 3.5


Does what it says!

Ease of use

1-second installation


didn't even need any!


didn't need

I used this to: testing users with different access levels


This plugin does exactly what it says. It provides the capability of using the same email address for multiple users.

Ease of use

Very easy to install and use. I entered four test users with the same email address. Everything went fine. Verification emails were sent.


There's not much to this plugin. Support should be minimal. I haven't required any support. Upgrades will be provided through normal link.


The documentation provided was adequate. Installation is via the standard Joomla installation manager. An update server is provided.

I used this to: I use this plugin on a master gardener site where there are occasional husband/wife users with the same email address. Data is collected for each user for various reasons, and each user requires their own record in the database. This plugin fixes it.
