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>Shortcodes for login, register, activate, and reset password forms</li>
<li>EMail activation option</li>

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.
