The Quicklisp mailing list is generally unmoderated. However, to reduce spam, a new member's first submission is held in moderation and must be approved or rejected. I try to take care of moderation promptly, but my schedule doesn't always allow for it. I'm looking for a volunteer or two to help me out.
Your duty would be to check your mail for moderation notices and allow any non-spam messages through via the Google Groups moderation web interface. This isn't an editorial position - anything that isn't obvious spam should be allowed. The mail volume has been pretty low, with a handful of messages per week.
Ideal moderators would be in a different timezone than me and check email on weekends and holidays. Anyone in Europe, Asia, Australia, etc, feel like volunteering? If so, please drop me an email.
