http://tech.groups.yahoo.com/group/cli_dev/ is closed. A poll of the group showed that this was the best course of action. The archives are still there. Anyone who was a member can still search the archives. Unfortunately, Yahoo doesn’t provide a mechanism for public message access for a closed group, so this is as good as I could get it. All messages are still there.
