Questions: Has anyone qualified for the 200 additional storage unit slots for their house? I'd like to know how that works.
1. Is it a deed form like the free Harvester Power? 2. Is it tradeable? 3. Do you get to chose which house to use it on? 4. Does it work on guild halls? ...................................................................................................................
1. Yes, it is in the form of a deed. You can choose it when you hit the 39 month milestone. It will be listed as, "(ONE PER ACCOUNT LIFETIME) A deed to increase house storage space (permanently raises the storage space cap on your structure by 200)"
2. No the deed is not tradeable.
3. You can use the deed on any player structure that has an inventory.
4. Yes, it should work on guild halls.
Some other things that are helpful to know:
* If you re-deed a structure that has the extra storage, the structure deed will be no-trade. * You CAN remove the extra storage deed from a structure and put it on another if you like.
To do that, you have to: o Make sure that the amount of items left in the house is at the structure's normal inventory capacity. o Go into your Maintenance Terminal and access the Structure Management Options. The option "Redeed This Structure's Storage Increase" will remove the Extra Inventory Deed from the structure and place the deed in your inventory.
Awaiting confirmation as to whether the deed will work on POB ships
