Due to issues with very large volumes of spam, the groups.io
organization made a change to their policies. Effective on October 7, new
members are moderated and will be unmoderated after 1 approved message. What
this means is that the first time a new member posts to this group, a moderator
will have to approve that post. Once the post is approved, they will be
unmoderated and will be able to post additional messages without requiring
approval.
