Guild Bank

From wow.incgamers.com

From patch 2.3, players can use a new feature called the Guild Bank. If you have done general banking before, you'll find that it's similar.

From Blizzard:

The Guild Bank is a shared repository for an entire guild and will be accessible through Guild Vault objects near existing banks. The Guild Bank will allow players with the appropriate permissions to store items and money for use by the rest of the guild. Permissions to withdraw and deposit money and items are controlled by the guild leader through the guild controls menu. The Guild Bank is divided up into distinct categories.

• Up to 6 purchasable tabs each containing 98 item slots.

Slot 1 = 100
Slot 2 = 250
Slot 3 = 500
Slot 4 = 1000
Slot 5 = 2500
Slot 6 = 5000

• Permissions to view/deposit/withdraw per tab
• You may use your Guild Bank withdraw limits to pay for item repairs (now enabled on all merchants)
• Transaction logs of the last 25 actions in the bank viewable on a per tab basis
• Access to the Guild Bank is made via the Vaults in the existing banks, as seen below.
