maybe the average rating would do you more good. Or you could get all to join a vote chess game and then check team members.
Ratings of group members

Those are good ideas but if I'm starting a tourny in a certain range I don't know how members I can count on.

How big is the group? If it's small enough, you could just grab a pencil and paper and go nuts.
I'd go nuts alright going to all 45 hompages to see their rating. By the time I'm done I'd have to start over. We can find their points all over the place but what good are these points. I need ratings not points

Being the super admin for a group it would certainly help if when I look at all the members that I could see their ratings in the member list so that I could organize tourny easier, Here is the group page I'm mentioning
A workaround was discussed here. Challenge the DUMMY GROUP and ask all members to join, while assuring them there will be no games to play.

Thanks TadDude, It nice to know that others consider this a probelm that needs to be solved. The main difficulty with the dummy group idea is you need all team members to participate. That ain't gonna happen!!. Any participation over 20% in anything from a group is surprising. Nothing against my members but that's just human nature
