In reply to Edith Allison.

I would NEVER support adding ads on the plugins. I am sorry. But no. There is enough abuse of my admin dashboard with "rate my plugin" "subscribe to my newsletter" and so forth.

I think the model of paying for support instead of the plugin itself is better than plugin authors abusing my admin dashboard with the pro version of the plugin or their other plugins. I don't even want to see the 40% sale you are holding in your site for the pro version of the plugin.
