Starting from next week, if you play on either Surf server between Tuesday and Thursday (midnight, server time) all base cube gains will be doubled. This means if you're after a certain item in the store, these times should help you out considerately! This is just a trial to see how well it works in the event we try out similar other features.
It's a good idea! It's the quietest time of the week, so some incentive to get on at those times. Might be worth clarifying what the server time is, considering different timezones across US etc.
