Dear John,

I have gotten so much moral crushing negative response for trying to do as you 
just suggested.

I am writing from an old computer right now, because after the last update, 
kmail wouldn't communicate with the ISP in my Jaunty box.  I installed Karmic 
in this old box.  Unfortunately I mentioned it in an email responding to a 
problem I was attempting to solve.  I got over 100 responses to my problem all 
relating to why I should not have installed Karmic and not responding to the 
post.  Everyone is so opinionated about what I should or should not do, that 
when this kind of problem happens, I can forget about getting the help I need.

Quite frankly, I consider my Karmic box experimental with potential problems, 
but it has saved me twice now and I have only had it installed about a week.

There are a couple of people from the list who have discouraged me from using 
my own ideas.  And, I have found that if I take the advice and practice it 
enough it becomes learned memory.  But if you remember from the email you are 
responding to, I have a lot of trouble using google  and man pages.

It is spirit breaking, because I know that if I could just use the left brain 
hemisphere, I would be just fine, but the way it is, my searches lead to mental 
overload and confusion.  I hardly ever read a man page or google something 
where I am not redirected so early in the answer of a problem, then redirected 
from the redirection, on and on that I end up overloaded.  

Computer people seem to just wade naturally through the data without problems, 
but they are always talking about stuff I know little to nothing about, and I 
never know if the transfer is necessary to understand before I return to the 
problem I was looking for answers to, so I keep going until I reach overload.  
And by overload I mean,  reading something intently, but unable to make any of 
what you read understandable; you end up bleary-eyed and frustrated, and can't 
continue.

For some reason, today I have been getting the most helpful responses.  
Answers that I can receive and understand.  It is glorious.  Thanks for the 
great reply, my friend.

Steven
