			== Specific Actions ==

			At the meeting specific activities were planned:

			* Possible fabrication of a patterned substrate for intercomparison of grazing incidence scattering will be investigated (Sarah Rogers) and circulated for discussion.

			* Groups that have been involved in the latex Round-Robin have been contacted to obtain necessary complementary information for a publication (Adrian Rennie). It was considered desirable that at least one X-ray data set be included in the publication if possible.

			* The glassy carbon Round-Robin samples are being returned to Europe (from ANSTO) for further measurements of neutron transmission as a function of wavelength and inelastic scattering at ISIS and ILL. These are scheduled for September 2012.

			* ANSTO and ISIS are sharing information about proteins as standards and for intercomparison.

	The results described arise from four full days of intensive work in small groups during the meeting in Uppsala and from preparatory work. We acknowledge the generous support of the agencies employing the particpants that have made available time and travel resources to permit the co-operative work. We are also grateful to people who have given freely of their own time to support the SAS community. Just the direct participation amounts to about two-person months of effort. These 'sponsors' are APS (Argonne National Laboratory), NCNR (National Institute of Standards and Technology), ISIS (STFC), the Diamond Light Source, Institut Laue Langevin, University of Auckland, Kyoto University, University of Tokyo and Uppsala University. We are also grateful for further participation from ANSTO, APS and ESRF in webinars and by making contributions to discussion on the wiki.

In this area it was felt that not too many new projects could be initiated at one time. It is probably most efficient if they start with work at just two or three facilities. When an appropriate sample or samples have been prepared and initial data collected, these can be broadened to include a wider range of participants.

	* Several fields were identified as likely to benefit from new round-robin activities. In practical terms it was thought best to initiate only two or three new projects immediately and that these should first be started by a small group of two or three participants. They can then be widened when initial materials and data are available.		* Several fields were identified as likely to benefit from new round-robin activities.
