TIP locate a USENET FEED using GG2
At the top of the page you should see a link to MORE, click on it. Then
you get a summary of statistics about that USENET feed.

BTW you can activate a ATOM FEED from there so you can read new posts
in your ATOM/RSS news aggregator. You do not need a USENET News reader
with GG2

You don't have to 'join the group' for this to work. In the table of
summaries about the number of posts per month click on one. This opens
a framed window of all those posts. Click on a few, scroll; look
carefully at the left frame while you scroll the right frame. Do you
see it what I noticed? Enjoy if it works for you too.
