This plugin adds a separator between the intro text and the extended (more…) text of the content of a post. It simply replaces the span id more tag with the separator that is set in the plugins php file.
Some separator samples are given there.
Upload into the /plugins directory and activate it in the Plugins Menu.

<h4>Because “read more” isn’t good enough</h4>
Turn your “More” links into a bespoke call-to-action for each post. Rather than have “Read more” or “[…]” after your excerpt, you could have “See Bob’s garden up close” in a post about a beautiful garden, or “Try our tasty sauce” in a bolognese sauce recipe.

ActionPress

Still works

Replace the [...] more link with custom text for each post, creating a specific call-to-action.
