You could try out your proposal for a while with a small test group of people to see how it would work out. Maybe come up with a sub-catagory of DCS members like a catagory about children or divorced for a long time catagory or manager catagory, or something like that.
Try it for a year or so with a dozen or so people, and then if MSN decides to change their groups,a plan would already be in place.
