where on the dashboard do you specify your rss url?

Hi,

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!

Thanks
