Some neighbors are great - others have been extremely rude. Yelling out the courtyard. We had a really rude, anonymous letter left on our door, cursing at us, but it was clearly meant for someone else and they got the wrong apartment. I'm not sure if this protal has the capability, but it might be nice to have a virtual community bulletin board where neighbors can talk. Maybe issues would be better resolved.
When our downstairs neighbors moved in they politely knocked on our door, letting us know that it is extremely loud. We had no idea how loud we had been, but since they calmly and nicely brought it to our attention we have been respectful and they have not complained since.
I don't think people realize on higher floors how loud it is to their downstairs neighbors or how much you can hear in the courtyards with the echoes. Might be nice to bring to people's attention.
