I found a Facebook widget I would like to use. I searched the WordPress help files and found the installation instructions. The first line reads
"Add a directory called 'add-to-facebook-plugin' (without the quotes) to your '/wp-content/plugins/' directory."
How in the world do I complete this action??? I do not know where this plugin directory exists, let alone how to add something to it.
The blog I need help with is tuscaloosadu.wordpress.com.
