Indeed a good new approach from Teamlava. However, neighbors send request on all materials needed to all neighbors. This mean, one neighbor may receive few materials at the same time but that one neighbor can only send out one gift and have to decline the rest one by one. Turned out, what I do is, I send one request to one particular neighbor for one material at one time. This really time consuming. Hopefully Teamlava may come out a better system on this SOON.
