The following changes were made since our last communication:Users can now only join a Yahoo Group through an invite or group request approval by the Group Moderator.New Groups can’t be public. They can only be private (not listed in Groups directory, membership by invitation only) or restricted (listed in Groups directory, membership requests must be approved by a Group Moderator).Members must share all content via email, and can no longer upload or host new content on the Yahoo Groups website itself.
