I'm about as done fixing my own plurk's layout as I'm gonna get (at least for today), so I'm gonna go ahead and offer it up in case anyone's interested in a dark, aquatic theme or just something that has most if not all of the plurk elements put down to be played with.
I incorporated several of the fixes here, so thanks to dood for the userpic thing, farrons and freesia for hiding the badges, and hypeodermic for helping squash the yellow highlighting!
