This is a free add-on for the Newsletter plugin that allows publishers to hide specific parts of their blog posts, revealing the content only to confirmed newsletter subscribers. It's designed for content creators and site owners who want to use exclusive articles or sections as an incentive to grow their email list.

• Selective Content Locking: Use a simple shortcode to wrap any part of a post, from a single paragraph to an entire section, making it invisible to visitors who haven't subscribed.
• Full Post or Category Gating: You can lock all posts within a specific category or tag completely, showing only a title and a subscription prompt to non-subscribers.
• Customizable Call-to-Action: When content is hidden, a configurable message appears in its place. You can set this to display a simple text prompt or automatically show a full subscription form.
• Automatic Access Management: Once a user confirms their subscription, a cookie is set to automatically unlock the gated content for them on subsequent visits, without requiring them to log in.
• Admin Visibility: The hidden content remains fully visible to logged-in users with publishing privileges, such as administrators and editors, allowing for easy content management and preview.
