What makes you think it is members only?!? NTFS-dev is not members only at all. It is moderated which is a very different thing. Most list members have to be approved for posting, too... And the only reason it is moderated is spam filtering. We delete 99.9% of emails going to the list by hand as moderators because they are all spam. That means the list and the list archives only contain NTFS related messages and not thousands of posts trying to sell you pills and what not...
