The author says: "You can select whether you want them displayed on your posts, pages, or your home page."
This is NOT true.
It will either show on ALL the posts and pages or NONE.
What use is that?!
There are other concerns like the popup continuing to show for those already subscribed to list.
The Author is also absent for a long time and the plugin hasn't been updated, and there is no follow up in the Forum.
