I have read the documentation about the variosu rss feed urls that you can have for your site eg http://www.yoururl.com/wp-rss2.php
But when I can't find anywhere where you specify what option you want on the wp dashboard.
And when I look at the template, the area on the sidebar that inserts the url is:
<?php bloginfo('rss2_url'); ?>
which gives me the impression that the url for your rss feed is supposed to be specified somewhere on the dashboard...
Any help appreciated!
