Hello Dave,
Sadly we have to deal with the world as it is rather than the way we would like
it to be.
Sure. Does this mean we won't try to educate them?
Far more people use the wonderful MicroSoft products such as Outlook
than use all the alternatives added together.
Indeed.
Please can we try to be less unfriendly to people that are new in here?
Am I? Sorry if my message seemed like that, because it was not the intend.
Top
posters (first timers asking questions) need to be responded to at the top of
the thread. Otherwise they might assume there was no answer in the reply.
If you read this very message, you can see that I've edited it in many pieces that are very likely to be noticed. I guess 
So, top- or bottom-posting is just a part of the "mail-user-education": editing the original message to get to the point is also very important. The sender must think he has to be read, and understood (otherwise what's the point at posting at all?). So eliminating the useless parts -- which are available upper in the thread anyway -- is a requirement.
The first thing that most people see is the top of the email and
almost all our responses fall into the "leave to later or delete straight-away"
category.
This is what message editing is all about.
Yes, they don't do thing 'our way'. Obviously 'our way' is the only 'right way'
but that doesn't necessarily mean we don't want to help them. Or does it?
No, of course. This is my point: bottom-posting + editing and, from time to time explaining. I don't think I ever ignored any message just because it was top-answered.
Cheers,
