Okay, Rick knows how to do this, but he's on vacation til next Tuesday and won't be checking his Radio News Aggregator. He told me how to do it, and I had this in an E-mail saved to use if I needed to. You have to understand a bit about Radio, but I'll post this and let the others explain in more detail. The stuff in bold is a variable that you create. Here's the recipe:
"You need to know the ftp username and password for your web site. if you
don't have it, get it from whoever maintains your site.
go to:
http://127.0.0.1:5335/system/pages/prefs?page=6.3
create a new password. name it "whatever" (no quotes). In the password boxes,
put the *password* for your website ftp password.
Now, create a text file in Notepad. It should read:
<upstream type="ftp" version="1.0">
<username>[INSERT FTP USERNAME HERE]</username>
<passwordName>whatever</passwordName>
<server>[INSERT YOUR WEBSERVER FTP NAME HERE]</server>
<path>/news/</path>
<url>http://www.yourblogurl</url>
</upstream>
Save the file as #upstream.xml in your category folder."
