The Academic Users' Group (AUG) is comprised of academic health centers who have implemented i2b2 or are interested in implementing. Every year the i2b2 Foundation and the SHRINE Team hold a conference where members of the AUG gather to support awareness of related activity amongst members of the community, stimulate collaborations on developing and/or modifying elements of the i2b2 software to better suit local or broader needs, and to provide guidance to the i2b2 team on issues ranging from software licensing to management of version control to collaborations with industrial partners.
