This plugin was developed because I have one blog with multiple authors who have 
their own categories. The users’ category access is administered by the Authors2Categories 
in Tools panel of the admin.
Select the user. Click on Edit User (Tools>Authors2Categories) and select the categories he/she 
are allowed to post to. Click on Save when you are done.

Author Category Revival allows site administrators to control which categories each author can use when writing posts. Administrators can assign specific categories to authors and set which categories are checked by default in the post editor. Authors no longer have to worry about managing categories or figuring out which ones to select.
What the author sees:
<ul>
<li>Only sees categories assigned by the administrator</li>
<li>Sees pre-checked categories as configured by admin</li>
<li>Can change checked categories within allowed options</li>
<li>Cannot see or access categories not assigned to them</li>
</ul>
Key Features:
<ul>
<li>Author Restrictions: Restrict authors to specific categories only</li>
<li>Default Categories: Set one or multiple default categories (or none) that auto-check when authors create posts</li>
<li>Hierarchical Display: Categories show in parent-child tree structure</li>
<li>Real-time Preview: See exactly what the author will see in their editor</li>
<li>Quick Actions: One-click select/deselect all or parent-only categories</li>
<li>Admin Protection: Administrators are never restricted</li>
<li>Multilingual: Full French/English translation support</li>
<li>WordPress-like Interface: Seamless integration with WordPress admin</li>
</ul>
How it works:
<ol>
<li>Administrator goes to Users → All Users</li>
<li>Edits an author profile (cannot restrict own account)</li>
<li>Finds “Author Categories Management” section</li>
<li>Selects allowed categories for this author</li>
<li>Clicks “Validate your choice” to update the preview</li>
<li>Checks default categories in the preview (optional)</li>
<li>Saves changes with “Update Account”</li>
</ol>
