In polling the UC reps, it seemed that there is broad support for this initiative. People agreed that this would enhance the scientific impact of APO over time, and no one seemed alarmed that the data would become public (after some proprietary period), particularly if there were a way for a user to opt-out. Nancy will provide more updates as they become available. |

| - | Gordon is working on a new release for TUI (v3.2), which will be coming out soon. The new version cleaned out some old scripts and removed the option of selecting instruments that are being decommissioned. The most exciting aspect is that he is working on packaging to make the software installation process more simple for users, especially students. Although we encourage users to stay current with their TUI versions, older versions of the software will still work. | + | |
