Hi everyone. I’m fairly new to the game and still trying the learn the complexities of land over runways, upgrading over rocket launches etc. I’m not sure I’ve grasped it but I’m doing my thing. 
My immediate question is relating to neighbours. I have several Zzz, does this mean that they are inactive and I should delete them?
Thank you 😁
