It's at:
http://your.site.com/path/to/blogs/xmlsrv/rdf.php?blog=N
and
http://isaacschlueter.com/xmlsrv/rss2.php?blog=N
where N is the number for the blog that you're showing.

For example, my blogs are at http://isaacschlueter.com, so the RSS feeds for my "all blogs" aggregation (blog #1, that shows all posts from all blogs) would be:
http://isaacschlueter.com/xmlsrv/rdf.php?blog=1
http://isaacschlueter.com/xmlsrv/rss2.php?blog=1

Note that most [url=http://skins.b2evolution.net]skins[/url] have a "RSS" section with links to all the feeds. Also, check out the source of your blog page, and you'll see some "LINK" tags up in the HEAD that look something like this:

	<link rel="alternate" type="text/xml" title="RDF" href="http://isaacschlueter.com/xmlsrv/rdf.php?blog=1" />
	<link rel="alternate" type="text/xml" title="RSS" href="http://isaacschlueter.com/xmlsrv/rss2.php?blog=1" />

Thanks!
