More accurately, 97% of the sites have it in their active file. My arbitron report shows 0 readers in every group that I don't get. I asked Brian about that, and he said that he expected that sites that didn't get groups would not have them listed. Arbitron cannot distinguish between a group not received and a group received with 0 readers unless your active or sys files indicate it. -- : Michael Gersten uunet.uu.net!ucla-an.ANES\ : ihnp4!hermix!ucla-an!denwa!stb!michael : sdcsvax!crash!gryphon!denwa!stb!michael : "A hacker lives forever, but not so his free time"
