A little thing that continues to bother me is hiw hard owners must sometimes work to support a new group... which generally seems to be greatest until a list has ~100 members... which I always called, "critical mass."
Will "100" and success at the owner's doorstep encourage them? Or finally reaching some stability, be 1 more nail in the coffin due to a tired owner and actually raise the number of failing new groups...? Tough call. Good luck.
