The April Townhall is scheduled for Tuesday, April 4, at 10:00AM CDT (15:00 UTC). It will be held in the Argonne National Laboratory venue on the institutional venue server (Go to https://ivs.mcs.anl.gov:9000/Venues/default, then Government Institutions Lobby, then Argonne National Lab). We will discuss topics of general interest to the community, including the AG and collaboration in general, and AG2/AG3 and the AG Retreat in particular. This is an open forum for the community to air issues, new collaborations, and innovative ideas; please come prepared to participate. There will be a second session held for those in the Asia-Pacific region, on THURSDAY, APRIL 6 (Note that this is a different day!) at 6:00PM CDT (23:00 UTC). Of course, anyone is welcome to attend this session, if it's more agreeable with their schedules. ANL will be running bridges in the Argonne venue for these meetings.
