Many in my neighborhood dont help ir respond same in my fellowships- it not fair in my opinion so i help those who help me-on the left of your city are little tabs one looks like a bell you can see who is helping you-help them! Dont waste coins on the others many have lost interest in the game and check in just to catch up but dont help anyone
If you are not receiving help from most of your fellowship, then I would say you are not in a very good one. If you are highly active, you may want to look for a new home.
[EDIT: I went and looked up your group, and they are very new and full of very new players. Do they auto-accept applications? This may get you a lot of folks who try the game out and then quit shortly after. As I said above, if you are active and plan to stick around for a while, start looking for a better FS]
Neighbors, on the other hand, that one can be more tricky. How many pit mines you have around you, and the timing of aid can contribute to less reciprocation. Also, which may seem counterintuitive, if there are a lot of "big" cities around you, you may actually receive less aid. Large cities are rarely in need of coins and supplies, so while they might return aid if they catch it in their notifications, they could be less likely to roam around the map giving aid to all of their neighbors.
