I just created this new Drupal 7.12 site with Softaculous, and added a quick Artisteer theme.
Right off I noticed a Read more link even though the teaser = body and there's nothing more to read. Researched this (again) and didn't find a specific solution. There is a Read More Link module that advertises moving the Read more text from the node link area below the teaser/summary to inline or on the line just below so it will show up in RSS feeds and otherwise which would leave off that link Field. I went to upload this module to try it and didn't see the install a new module button. More research revealed that I had to enable a core module Update which I did, then saw the Install button and used it to install read_more-7.x.-1.x-dev. There is no configuration for this to turn off the read more when the body = teaser. There is a no display option if the Body is empty so I moved this text to the Summary, left the Body empty, and still got the Read more link, now Inline. This typing is in a Summary. There is still a useless Read more link that goes to an empty Body. This is a real good example of why I don't like Drupal.
