Could you add an option in the config, so you can choose if members of a force field are allowed to place and destroy blocks?
So it would be possible to build large protected buildings together by adding member to your own field.

well i just tested it and it works :D
i think there was a fault in my database at the moment i tested it.

sry for posting this issue.

Players allowed into your fields can already place and destroy blocks. That is the point of the allowing, not sure i understand the request.
