This component provides the ability to manage users and roles from frontend. It is possible to do CRUD(Create, Read, Update and Delete) operations from the frontend. The administrator can only add, delete the user and assign the particular group (like Author, Manager, Editor, Public etc.,) to the user.
This components is a good solution for administrator that can assign a particular user to manage all the users by just adding him to UMS category.
When you add a user this component checks for username, if the username already exists, then this component will not allow a duplicate username. All input fields have validation.
For User Management not need to login to backend . User management system can properly work on Joomla 2.5.x. and 3.x
