This workshop will serve as a meeting point for users and developers of Macaulay2. Its goal is to bring together researchers who would like to improve or share their skills at writing packages and those interested in developing the corresponding mathematical algorithms. There will be groups working on packages for numerical algebraic geometry, algebraic statistics, and enumerative algebraic geometry, as well as participants developing new and old packages not necessarily related to these topics. For examples of possible projects see our past workshop topics at http://wiki.macaulay2.com/Macaulay2 Notes for participants: Attendance at this workshop by invitation only — based on a brief application — and all who are interested are encouraged to apply. Financial support is available for approximately 30 people with preference given to younger researchers.
