The Trinity has ruled! Guess I can be on top or bottom as long as I keep it short.
Thanks guys, I will quit fretting about it and let you now ponder world peace.
No. You should fret about it. Not only will you give the impression of being a boor but there are practical reasons for BOTTOM POSTING.
This is a piece of etiquette that is being lost in part due to Microsoft putting your cursor at the top when replying and in part just due to the trend towards wearing your pants on the ground.
You should post below the text you are referencing. That way people have context for your reply.
If you are responding point by point in a large quote you should insert your responses in the quote below each point you are responding to.
Note: quotes start with "[qu ote]" and end with "[/qu ote]" You can insert these in the quoted portion break it into multiple quotes and respond in between those.
If you are responding to a large portion of text and only a small portion of it is pertinent, then EDIT the quote to delete the large amounts of unnecessary (to understand your response and what you are responding to) text or pics or whatever. Don't be lazy. Don't wear your pants on the ground.
