Tag Search is a simple little tool you can use to automatically create links in your posts using your tags.
Backup your WordPress database and files before you install or update.
Upload the file and unzip it to the wp-content/plugins/ directory.
Activate the plugin.
Go to the Settings > Tag Search and configure the few options.
That's all there is to it. As long as everything is working and there are no conflicts with other plugins or your theme Tag Search should be functioning.
