aggr allows you to place the contents of an RSS feed into your pages or posts. It is a deeply modified version of the Aggregate plugin of Rob Miller (I also used an idea of Michael Jolley).
To install and use it, download the zip file (latest release: 1.1), extract aggr.php, upload this to your wp-content/plugins/ directory, activate the plugin in WordPress.
To use it, add one or more lines to your page or post like
<!--rss url="http://perassi.org/feed/"-->
If you need a widgetized version, try aggrw.
ChangeLog:
- Version 1.1 (2007-12-10): it adds
$item_countand$title_lengthwith code closer to what suggested by Scott; - Version 1.0b (2007-09-03): it fixes a small typo;
- Version 1.0 (2007-07-07): first release.
