WW sorted the list into 3 categories, people with no posts, people with less than 10 posts, and people with more than ten posts, at least I think that's how he did it. He then made us, the people with more than 10 posts, look normal and made everyone else grayed out. This keeps you from having to look through 20 names you don't know to find out that 5 people on Zelaron are online.

The numbers above might be wrong, but that's pretty much what he did.
