This is rBBS_Diablo2 a layout style for the rBBS framework. It creates art based on the game Diablo 2.
Use the rBBS menu gem or the /rbbs slash command to open the menu. You can do the following things ingame: lock, unlock, show, hide, resize, scale, move, reset.
Version 1.03 introduced a new API function, the dragframe. If you want to make use of it create it first in your layout and have other frames parent it. (See example layouts). If you move/scale/resize the dragframe all hooked frames will follow.
