We have a site (http://www.techwr-l.com/)that archives the email discussions (we tried to merge these forums with the email list a couple of years ago, but the technology failed miserably). I've pasted some of the key instructions below. If you have any issues just reach out.

Please note that the first postings from a new member are moderated. This helps reduce the "post and go" spam issues, and also catch some messages that people didn't really intend to post. Even if you've been on the list for years, but you've changed your address, postings will be moderated--the server has no way to know that you're the same person after a change of email address. We are not informed of who adds or leaves the list so if you do change your address, please contact us and we'll update the system. We normally remove moderation after a week or so of posts for new members.
