Looks like Surii set up the Guild Bank addon, Duckiebank.
First off, download it here: World of Warcraft UI / Mods - The Unofficial World of Warcraft Mods site
Extract it with an unzip program to your WoW Directory, under /Interface/Addons/
Make sure to select to use existing folder names. It's usually the default selection in Unzipping programs.
After you do this, you should be able to restart WoW and see the little bank bag by your minimap. You can choose between the 2 bank characters from there, and pick which items you would like to request.
Hope this helps!
