The parents of Lauren Spierer, an Indiana University student who has been missing since June 2011, are upset with the university over a change to its website.In a posting on the family's Facebook wall, Robert Spierer said he and his family are "disappointed" with the university's decision to scale back the posting of information related to the student's disappearance. Special Section: Lauren Spierer "Lauren's once prominent banner on the Indiana University website homepage was months ago reduced to a button, and now Indiana University plans to only post the link to Lauren's information on the home page the first week of every month," Spierer said. "It will appear only randomly thereafter."The university confirmed to the Bloomington Herald-Times that it had made a change to the site to rotate information about Spierer with other items."We are disappointed by this decision, as we hope to obtain information from the IU community which will lead us to Lauren," Spierer said. "We are still determined to do everything in our power to find our daughter."Lauren Spierer, who turned 21 last month, was last seen in the early-morning hours of June 3 after a night of partying with friends.
