Meanwhile the environmental situation is worsening. I would suggest we try another moderator-free period. A very brief reminder of expectations could be added automatically to each post. Complaints can be dealt with by a council, as the list had for some years. Therefore the list appreciates short posts.
Nobody is perfect.
Therefore be polite and stay polite. The aim of this list is not primarily debate but the development of viable socio-economic solutions for worrying environmental developments. Solution-finding benefits from sticking to the Subject of the post as closely as possible. Every co-lister is in fact moderating the list. The list recognises its responsibilities and encourages participation.
