BuddyPress.org

Is there a way to restrict user from creating groups? I only want the administrator to be able to create groups in our site. Right now any user can go into the site and create a group. Our IT group has logged this as a security concern so we need to lockdown our site. An administrator should still be able to go ahead and create a group, but that should be it. I’m relatively new to WordPress so any information or help would be greatly appreciated.
