Bugzilla itself has indeed been improved over the last decade.  Now, if a 
cursory search come up empty, it will actually give you a file new bug 
option.  I can remember when you had to wade through the whole database 
before it would let you post a new one.  That, when the database has 15 
years worth of bugs it takes a 400wpm reader a day to slog through, was 
simply not acceptable, and I was just one of many to raise all sorts of 
hate and discontent about that ill advised "feature".  I used up a goodly 
portion of my 5 minute monologue developed for use when I have hit my thumb 
with a hammer on more than one occasion at some poor hapless soul.  The 
current version is indeed a huge improvement.

When you have had the access battles with bz I have had, believe me that is 
the impression I come away with.

Yes, considering that among the 40 or so I am subscribed to, some of which 
have several hundred postings a day(like lkml), I would agree that is a 
charitable estimate.

I am retired so that is moot, (and I don't read all, likely a quick scan of 
the subject & who its from & go on in about .7 seconds) what is not moot is 
the need to get out of this chair and go loosen up the stiff joints of old 
age and do something that might look like work to some, keeps me out of the 
bars etc.  ;-)  Currently plotting on how to get a few hundred bd/ft of 
wild cherry the wind took down almost a year ago, in the form of 6 or 7 
foot logs that I can get sawed up at a mill about a mile away.  The downed 
trees however, are about 150 feet up a moderately steep hill about a block 
away, in 60+ foot pieces that are thicker than my chain saws blade is long.

A good example to be sure.

Which is not where I just took step one of creating a new 'me'.  I see 
there are 2 msgs in that folder, perhaps one of them will be step 2.

Thanks Ingo.

Marvelous!  The super-user's going to boot me!
What a finely tuned response to the situation!
