The following files are OPTIONAL files and merely change certain aspects of the Fetish UI, that deviate from the Original UI:

~ eq2ui_community.xml
  * Incorporated /tell and /invite buttons

~ eq2ui_inventory_market.xml
  * Added in the Broker points (I'm sure this is useful somewhere)

~ eq2ui_mainhud_groupmembers.xml
  * Members frames within the window made slightly longer.

~ eq2ui_mainhud_mail.xml
  * Added in current coin (on you) into the "inbox" and the "send" tab.

To install any of these files:

1) BACK UP YOUR EXISTING FILES! (rename them or move them to a backup folder!
2) Copy the one(s) you wish to use
3) Paste them into the FetishNightfall directory, be sure to click YES to replace!  

****************************************************
DO NOT USE EITHER OF THE OPTIONAL TRADESKILL FILES,
THEY ARE STILL UNTESTED AND MAY CRASH YOUR GAME!
