Currently if I would wanna let others not in guild use my silo's the only option I have is to put my plot on friendslist which would close off my plot for a part of the community, something I don't wanna do or set the silo on All.
I would like to see that I could set a friends list on each silo I have so I could set rights on a silo that one person could use it or a group of ppl.
For example when doing an event then the silo could be filled with resources before the event starts but a guilded player would have to unload the silo's then something which wouldn't be the issue if you would have a friends list.
You could also rent the silo's when you would have a friend list option like this for each silo.
