Three years ago Wuala and LaCie joined forces. To celebrate the anniversary of this notable event, Wuala increases included storage from 2 GB to 5 GB. If you are already using Wuala, your new storage quota will be available over the next few hours. All you have to do is to sign into your account again to see your updated storage.
