I can't tell if my salvage stations, which I do have a settler assigned to each one, actually do anything. I don't have the local leader perk - it would cost me 7 freaking points, since I consider everything else in the tree useless, and I've read reviews that say the charisma locked options usually do not let you avoid violence, just boost rewards - so I don't have the supply and merchant options. A friend told me that if you do have that perk, settlements bring in mad caps, such that you can get tens of thousands of caps very easily. Maybe I should have gotten it - it would make it a lot easier to buy adhesives and keep my power armor charged.
