Thanks for your replies, Jonathan and Alex.


I don't know what an RSS feed is, but if it refers to new stories or 
accessing news in real time, that's not what I'm doing.  I want to tap 
into complete archives.

	Yes, exactly.  I thought about that.  It'll require some tinkering.

	Thanks.  I didn't know about robots policies.  So, I'll request that
