Ronaldo,
That 'Announcement Group' setting is especially useful when one is setting up a new group and preparing for a transfer from YGroups to GIO, but hasn't yet announced the impending move to the membeship of the already existing (old) group. The 'Announcement Group' setting effectively keeps members of the original group from subscribing and/or posting to the new group until the owner has it completely set up and ready to go.
And during the set-up time of the new group it's also helpful to change the Privacy Setting of the group so that it is not listed in in the directory. This keeps anyone from accidentally finding the new group annd attempting to join it 'til the owner has it ready for use by the membership.
Finally, once the new group is ready and the transfer of the membership and other data is complete then the membership of the original group can be alerted and the settings of the new groups can be changed so that it is available for posting to and is also listed in the directory.
This arrangement worked very well for me while I was preparing for the transfer of my group from YGroups to GIO!
OK ¨C Hope this is helpful.

[Mod Note: Setting up a group as Announcement does not keep people from subscribing.]
