State officials are investigating a Web site that charged New Jersey residents $9.95 to fill out voter registration forms.

It's unclear how many New Jersey residents used IWantToVote.com.

Voter registration is free, and the forms must be hand-signed and mailed in.

State Public Advocate Ronald Chen said during last week's presidential primaries, he heard from three people who tried to register to vote on the commercial Web site. They were turned away at the polling place because they were not officially registered.
