Looking through the setup, I see that I have to enter the url: https://www.addthis.com/secure/ssi_callback
Why am I adding in a callback to another website other than my own, and why am I not inputting my own secret key?
Is there not a way that I can run this plugin entirely on my own server?
If there is, does this plugin work with multisite using subdomains?
Does it work with woocommerce?
Does it work with domain mapping and wpml (multilingual websites using different domain names per language)?
