So here's a question that has been bothering me: I read that we can only RECEIVE a certain number of items per day, but I thought I remembered at one point reading that we could only request help from 20 neighbors per day, or that only 20 of those requests would actually be sent out on any given day. So, I'm wondering what the best strategy for getting all of the donations is. Should I request Donations from ALL of my neighbors, or should I pick the 20 most likely to respond and only choose them when prompted? Any insight people have into how this part of the game works would be appreciated.
