1. My name is Donald.
2. Nothing makes me happier than having information archived in an organised manner.
I said earlier that collecting information in one place is a good thing. But I can't find things in massminds, so I don't go there. I don't understand what the organisation is and I find it cluttered. Putting the same information you included in this message into a file would have been helpful, permanent and allowed first time visitors to find it without guessing what keywords to search the lists archives with and dig through thousands of messages.
No, I won't put that information into a file - it's from massminds, so it's not mine to reproduce.
JMO. (and my last word on the subject.)
Donald.
