One, it's the weekend and perhaps people are busy with that.
Two, all the mods are unpaid volunteers doing so out of community spirit and giving of their own time. And as I understand it several mods view the work and moderate so it's not just one person passing judgment. They're not here as fulltime paid employees to moderate and approve skins, walls, etc.
Three, there may be a lot of things awaiting approval and some work may be ahead of yours.
Four, two days isn't that long a time so be patient.
