Actually........ there are long established rules for quoting, pre- 
dating the BBS and Internet days.

It's like those rules about not driving through flashing red traffic  
lights in my country. We have a lot of people that never heard of the  
concept when they were younger, and thus we now have a lot of people  
in my town that simply don't follow that old rule either.

;^)

So, here is a link to those nearly forgotten quidelines.......

http://www.dtcc.edu/cs/rfc1855.html

Allow me to quote a couple of those.......

******************
[from] 3.0 One-to-Many Communication (Mailing Lists, NetNews)

If you are sending a reply to a message or a posting be sure you  
summarize the original at the top of the message, or include just  
enough text of the original to give a context. This will make sure  
readers understand when they start to read your response. Since  
NetNews, especially, is proliferated by distributing the postings  
from one host to another, it is possible to see a response to a  
message before seeing the original. Giving context helps everyone.  
But do not include the entire original!

If you should find yourself in a disagreement with one person, make  
your responses to each other via mail rather than continue to send  
messages to the list or the group. If you are debating a point on  
which the group might have some interest, you may summarize for them  
later.

******************

They sure aren't laws. But they sure seem to be good ideas to know  
and follow.

Best to ya'
