Like To Keep Reading is a WordPress plugin that forces visitors to Like you on Facebook to access content on your website.
You can protect entire pages or posts, or just sections of pages or posts (our favorite) – i.e. your visitors can read the first two paragraphs and then must click the Like button to keep reading.
You can force visitors to Like your website homepage, any sub-page/URL on your website, or your Facebook page.
Like To Keep Reading also has optional Google+ and Twitter integration – so instead of Facebook Likes you can get Google +1s and Tweets from your visitors in exchange for access to your content.

This plugin hides the “Display Name” field on the Edit Profile screen for all users. Instead of allowing users to set this field, the plugin will always set the User field display_name to their first and last name. If these field are empty, display_name will be set to their username.
Display names are set when the user registers as well as when a user’s profile is updated via the WordPress admin.
The plugin includes a batch process to update the display name for existing users. Navigate to Settings > Force First Last in the WordPress admin to run the update.

Force First and Last Name as Display Name

Thank you for this simple and effective solution. It is something that should be part of WordPress by default.
Cheers
