This plugin solves two common frustrations with default WordPress user profiles:
<ol>
<li>Inability to Change Usernames: By default, a username cannot be changed after creation. This plugin adds a simple field for administrators to update any user’s username directly from their profile page.</li>
<li>Reliance on Gravatar: This plugin allows your users to set their own profile picture by selecting an image directly from the WordPress Media Library, giving them more control and overriding the default Gravatar. If no custom avatar is set, a clean placeholder image is used instead.</li>
</ol>
It’s a lightweight, secure, and easy-to-use solution for enhancing user management on your WordPress site.

I chose this plugin over another similar plugin which had more installs and reviews because this plugin offers a solution as simply as possible. No images or scripts needed, just plain old CSS for the win. Kudos to the developer.
