Cool, this way you could have a private store for each user. I wonder if you could also use this for roles and federated signups somehow. Also maybe you can enable primitive sharing if you use wildcards on both sides.

If it is a new washing machine there are breaks screwed into the back of the machine.

They are put there so the drum does not move during shipping from the factory to the customer, maybe they were also put in when you moved. If they remain in the washing machine motor is fighting against the break pads and the machine will shake violently. Please look at the manual or search on the internet how to take them out.
