A simple javascript script to make a substack-like subscribe here popup for ghost blogs
For folks who want to self-host a newsletter or blog, Ghost provides a wonderful option. However, it is missing a few features I wanted. One of these is a simple pop-up modal that encourages people to subscribe or share the post.
Download the script, modify the settings in the top part (comments in code) and then copy and paste into the footer code injection in the admin.
