I wish I could desinate group abilities

So all you cerified members could help me weed out the non-certified members that sign up :) Please let me know if any of you catch any. i go through the list once or twice a day, but it's a pain because when I find a non-cert member (and I do find them daily), once i delete them, it resort's the list, so I have to start from the begininning again. Not sure it will be possible to keep up with hundreds of members if our group ever gets that large -- really may need you help on that!
