Site update: new look of menu system  

The menu display has been changed from a tree-like menu hierarchy to a flat menu that rely on background color to identify their levels while the DHTML feature is still intact.

The more bright the background is, the deeper the item belongs to.

Underline indicates that this item has sub-menu. Single click on it will expand its sub-menu, while double click or a single click on the italic item with the same name from its sub-menu will bring you to the location this item points.

The item with a red box infront of it is the current item.
