Sorry but I couldn't come up with a good title. Anyway, I just noctied that if you hit select all when someone has posted code through the [code[ tags, that when you copy it, it messes up when you past it and makes whatever is in the code tags out of alignment. But if you manually select everything and copy and paste it, it displays fine.
I've added two screen shots, code1 is where I manually selected the code and copied and pasted it. Code 2 is where I hit select all and copied and pasted.
