The FAQ is a collective database of frequent user questions which the Edain Team and other members of the community have answered many times. They are answers which are unlikely to change and therefore there is little point in them being asked again and again. Therefore, before asking any questions, make sure to the check the FAQ out since it may have the answer to your question. However, if you don't find the answer you were looking for, you're more than welcome to ask a question on the either ModDB or Modding Union.
About the image:
This is the look of Isengard's new spellbook that will come in the patch 4.5. The spellbook is mostly centered around economy as it is the core of Isengard. Since Saruman is the central figure of Isengard, his role has been promoted: power Saruman of Many Colours now grants more bonuses to Saruman. Two spells were completely removed from current spellbook, 1 new central spell has been added and 6 spells have been balanced and reworked.
