Some things are best settled without a large audience. If you and another neighbour find yourselves in a dispute it’s best to take the matter offline rather than engaging in a public match.
If someone has done something that you feel is wrong, again best not to post a public notice. Try to resolve the issue with sensitivity and respect.
If you are in the process of organising for an item to be picked up or another type of transaction that is not relevant to the general community it’s best to use the private message function.
