After signing a petition using the EN Form block there's a "Share in Email" button displayed. Usually Campaigners have a nice email text crafted that could go into the email body.

I'd like to add a long text field in the backend of the EN Form block where you can edit this "Share in email - Email text"

Currently clicking on the button just adds the petition link to the email body.

Alternatively we could just remove the Share in Email button, I wonder if any living person ever clicked on such a thing.
