Re: nnml-generate-nov-databases - What Did It Do?

Some additional info (I'm counting on your having read the above before 
continuing).

Here's what the top of my summary buffer looks like (slightly edited):

 Gnus -- 200685  
   [  0   6]   1: advice    
   [ 90 941]  66: gwt  
   [ 67 337]  11: minix3    
   [  0   0] 200471: Archive.to  
   ... ... ...

Note the last line!  It appears to be a "subgroup" of Archive (there is, of 
course, a `to' subdir under `Archive').

Can I just "gnus-group-delete-group" that "group"?  I certainly do *not* want 
to lose all my archived, outgoing articles/letters.  So, I am proceeding 
cautiously.  ;-)

Ideas?  Thanks for any help/comments that you might provide,
