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

Implement various controls to customize membership, access, and appearance.

This plugin for WordPress adds a background-size controller to the Background Image section in the WordPress Customizer.
You can access the new controller by going to Appearance > Customize from the Dashboard, and clicking on the Background Image section.
Once you’ve added your custom background image, you can set your background-image size to: 
 – “Cover”: As large as possible; fills entire view, with cropping. 
 – “Contain”: As large as possible, without cropping; fits inside of view. 
 – “100% width”: Width fits view perfectly, height may be smaller or larger than view (equivalent to css ‘100% auto’). 
 – “100% height”: Height fits view perfectly, width may be smaller or larger than view (equivalent to css ‘auto 100%’). 
 – “Inherit”: Sets background size to whatever parent element is set to (html, in this case). 
 – “Custom”: Allows you to put in your own css to be applied in the section called “CSS for background-size (if ‘custom’ selected).”
To learn more about the CSS background-size property, go to:

<h3>Notes</h3>
Notes: 
*The plugin works by adding styles to the body.custom-background class. If the default custom-background support has been disrupted, then this plugin will not work.

Add Background-Size to Customizer

Allows you to control the background-size of your main background image from the comfort of the customizer, using predetermined values or custom CSS.
