Want to try a real server instead of Google
 

Go here and download Agent 3.3 · Build 846

Enter aioe.org for your server. No username or password.

One of the icons is "Open Newsgroup Directory"

This will allow you to search for the groups you are interested in.

You can hit "Begin Search" with nothing in the search field to get a
list of every group.
