How can I add summaries to the RSS feed? I only get titles right now. I set the use of summaries in the WP 3 control panel, but it doesn’t help. I've tried editing the sample RSS code in the user guide, but I can't make anything out of it; it's more targeted at creating a secondary RSS feed link if I'm right.
I also can't find the actual code in the template files for Thematic 0.9.7.x, which is what I'm running.
