Moth and ES, I claim no special clout in all this, and I suspect I'll be a bit part player if it gets going.

My instinct, for what it's worth, is that we should have an aim no more distinct than that

... we love "our sites",
... we deplore loss and damage through poor bureaucracy and commercial pressure
... and we want to make a difference through publicising causes in whatever reasonable and respectable way we can

Basically, that's how we all clearly feel here so it's got to be the right approach and we'll never need to change it and if Moth can find the words to summarise it, then great.

As for the details, I think unwritten constitutions work best so let's see what happens. If we need to grow then the need will show and we'll adapt as necessary.

Just my opinion though.
