#*** ARR prodded Ralf and it was updated. ARR - people need to send Ralf Schweinsinfo. ACTION: NIST and ISIS will update.
#*** http://www.ill.eu/instruments-support/instruments-groups/groups/lss/more/world-directory-of-sans-instruments/
#*** ARR - PRJ was going to look at directory of SAXS. PRJ is going to build a web page with form for people to fill out. Essential PRJ is on it.  Will await further report at next call.

#** KL - grounding and noise issues.
#* Long shutdowns
#** PDB - Repository of info about long shutdowns?
#** Could it go in SANS directory?
#* SANS/SAXS collaboration
#** ILL/ESRF can now do combined proposals for time on neutrons and x-rays. Initiative based around EMBL/ESRF/ILL - structural biology. ARR - noted that it is only for the biology programs. Any plans to broaden it? CF - in his mind yet, but nothing officially discussed. See if it works with biology and then makes sense to extend. CF will bring it up at next PSB/SAS partnership.
#** DC: BESSY2 and HMI combined center do it too.
#** ISIS/Diamond? SK - issues because Diamond is a separate entity. NT - need to discuss offline :)
#* Next conference call should be in late January, after the meeting at the ESRF.
