..."what is this site" box?
That's not very intuitive.
The only reason I figured it out is because I started clicking on everything below the "click below to jump to a page or create a new one:" and the "What is this site" box actually changed to a text input box.
I'll remember it now, but I'm sure there are others who have asked similar questions...
You might want to reconsider that design.
I'll get the signatures and sample code posted tonight when I get home.
