Audrey Rubin is feeling pretty popular. As chief operating officer of Aon Service Corporation's legal department, she has now been invited to join three networking groups for people with jobs like hers.

She's been attending regional meetings organized by Huron Consulting Inc. in her home base of Chicago for about 18 months. She's joining the Association of Corporate Counsel's Law Department Executive Leadership sessions. And in June she attended the inaugural offering of the Corporate Legal Advisory Series, organized by Marsh & McLennan Companies Inc. in New York.
