MGMC is a plugin that helps customize and control user login, registration, and content. You can customize appearance by doing things like hiding the admin bar. It provides shortcodes to place a login form on any page or post as well as to display content based on whether the user is logged in or not. A widget is also provided to display user information or links such as ‘Login’ or ‘Register’. It also provides an option for hiding the wp-login.php page to help avoid brute force attacks of that page.
Note that this control is primarily designed for site admins who will be running a site to disperse information, and not one where a community of users interact with the site.
MGMC also provides a means to share or validate users between sites with a validation key. The user must exist in both sites and be identifyable by email address. When a visitor logs into SiteA, that site can provide a link to SiteB with a special key so that when the user clicks it they will jump to SiteB and be logged in automatically. This ability can be extended to non-WordPress sites.
<ul>
<li>Change appearance by hiding Admin bar or dashboard</li>
<li>Widget for login links</li>
<li>Optional ‘Terms of use’ support</li>
<li>Shortcodes for login, register, activate, and reset password forms</li>
<li>EMail activation option</li>
<li>Disable users option</li>
</ul>
No changes are made to .htaccess or other WordPress files, so in the event of a catastrophic failure, you can just delete the MGMC plugin folder or all of it’s settings in your MySQL database.

MG Member Control

GuyPrimavera

This open source and lightweight plugin allows users with the role Editor or Shop Manager to access the Menus and Widgets areas of the Appearance menu in WordPress’ admin area.
This is a common task that would be useful for clients to manage themselves to give them more control over their website’s content.
This plugin also gives access to the Customize submenu and other theme options, but these can be hidden through the options page at Appearance > Editor Access if you wish.
You can also select other menus to hide from Editors and Shop Managers (e.g. custom theme or plugin options pages), as well as hiding any elements on the Admin Bar.
