If you’re the list owner or a moderator with the ability to add, remove, and change moderator privileges, then you can assign additional privileges to one of your co-moderators.

To assign moderator privileges, locate and click the member's email address in the Moderators section. The Moderator Privileges form is located below the Member profile. You can set the following options:

• Approve pending messages and photos
  Gives the moderator the right to approve pending messages and photos.
• Approve pending members
  Gives the moderator the right to approve pending membership requests.
• Invite and add members
  Gives the moderator the right to invite people to the group.
• Remove members and reset bouncing members
  Gives the moderator the ability to unsubscribe members and to reset bouncing members.
• Ban members
  Gives the moderator the right to ban members from the group.
• Add, remove, and change moderator privileges
  Gives the moderator to make members moderators or to change the privileges of existing moderators.
  Note: A very important power that should be granted only to people you trust.
• Set auto-send options for files
  Gives the moderator the power to send automatic messages to the group (like the welcome message).
• Change group settings
  Gives the moderator the power to change settings for the group. Another very important power that should be granted carefully.
• Delete this group
  Gives the moderator the power to permanently delete the group. Since this can only be reversed by Yahoo! Customer Support (and only within 30 days of a deletion), another power that should be granted very carefully.

To remove all moderator privileges, click Remove Moderator. This reverts the member to a regular subscription.
