Non-VIPs have no spacing, VIPs have regular spacing. (compare the use of white lines in owls, add a white line between paragraphs and VIPs will have way too much space in between, yet no white line is too little space)
In topics, with the exception of topic starters, everyone has no spacing by default, both VIPs and non-VIPs alike. But in owls and topic starters there is a difference, and it looks ugly and inconsistent. I vote that both VIPs and non-VIPs will all have no spacing from now on, in owls, topic starters, and topic replies alike.
Basically applied to the entire website, everywhere except individual coding if the user that coded that page prefers regular or double spacing of course.
Edit: should also be applied in homework, and any other affected areas of the website.
