Dear list members
I would like to request all list members please stop top posting and over
quoting. These are defeating the very purpose of having mainlg list. Please
go through this wonderful article on how to post message and reply in
mailing list.

I especially like http://www.netmeister.org/news/learn2quote2.html#ss2.3
which explains very well why one should bottom post. I quote:

2.3 Why should I place my response below the quoted text?

Usually, the reading-flow is from left to right and from top to bottom,
and people expect a chronological sequence similar to this. Especially
people who are reading a lot of articles (and who therefore would
qualify as the ideal person to answer your question) appreciate it if
they can read at first the text to which you are referring. The quoted
text is some kind of help to remember the topic, which of course will
not work, if you place the quoted text below your response.

Furthermore, that's the standard. This may sound as a weak argument, but
since people are not used to reading the other way around, they have no
idea what you are referring to and have to go back and forth between the
referenced articles, have to jump between different articles and so on.
In short - reading the article becomes more and more difficult - for
people who read many articles it is reason enough to skip the entire
article, if the context is not obvious.

And besides: doesn't it look stupid to first get the answer and then see
the question? (Aside from Jeopardy, of course.)
