Hi, in the group administration section of your admin panel there should be an option for this. Click the modify sign (
![Edit](/users/3412/19/22/63/smiles/1005357294.png)
) for a group, and you should be taken to the group settings page.
You should then see an option labelled 'Permission to send PM Mailings'. Make sure that members is
not checked and then members won't be able to send mass PMs to all the members within that group.
Repeat for all the groups if necessary.
