How to make WordPress RSS to only show the post title and exclude summary?

The current options are to either show the entire post or a summary of your post.

If you want neither, you will have to modify the wp-rss2.php file.

Add <?php /* */ ?> around lines 34, 39 to 52.

You are commenting out the <link> line, the <guid> line and the rest of the code that either prints the summary on the entire content.

Not sure why you want just the title, but here ya go. ??
