Instead of a shortcode <code>[closed-blog-helper]</code> shows a (customizable) message for the visitor according to their access rights to the blog.
Intended for use on multisite, but should work on single blogs too.
It recognizes five different situations:
<ul>
<li>Superadmin</li>
<li>Admin</li>
<li>Logged in but not registered on the blog (cannot <code>read</code>)</li>
<li>Logged in and can <code>read</code></li>
<li>Visitor</li>
</ul>
Message texts can be customized using few predefined keywords.
Developed for private use, but has perspective for more extensive usage. I can’t guarantee any support in the future nor further development, but it is to be expected. Kindly inform me about bugs, if you find any, or propose new features: zaantar@zaantar.eu.
