There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

With the help of Facebook, School of Interactive Computing Assistant Professor Sauvik Das and a team polled a random sample of 1.5 million Facebook users to find how they preferred to secure their profiles. Das presented his findings in a separate Enigma conference session, and revealed that a popular alternative to traditional two-factor authentication is Facebook's trusted contacts functionality.
