Gov. John Baldacci said he hadn’t been briefed on the program, but said that the list will not be posted on the web without a thorough public review.
The web site was to include information on roughly 10,000 people, and was expected to go on line within two months.
Officials see it as an aid to police and crime victims.
The online registry would be separate and different from Maine’s sex offender registry, which includes names, photos, offenses, and other information about convicted sex offenders.
That site came under intense legislative scrutiny since two men were killed at their homes in 2006 by a gunman who tracked them down on the web.
