the wonderful land of oz
or in some cases, a white folder means someone with the same internet provider [usually in the same city] was the last to post in that topic.
ie. if brian [lp] started a thread, and i was the last to reply, it wouldn't get bumped and there would be a white folder. as the pip system recognizes anyone in winnipeg using shaw as the same user.
a nice little technical glitch.
other than that, all of those little details are really convenient.
i'm so bitterly disappointed. betty, i think it's time you leave now.
