Add New Users lets you quickly add multiple users to your site without wearing out your mouse clicking “Add New”.
Key Features of the Add New Users WordPress Plugin
This plugin has been so popular with Multisite and BuddyPress site owners that we’ve made it available for single WordPress installs. Create and add new users in bulk batches of 15.
Creating and adding new users to a site is now as simple as entering a username, an email address, a password (if you wish) and select the level of access to grant to each user.
All new users will receive an email containing their new username, password and login link.
