After a short hiatus, the BEST conference is back this year: http://math.boisestate.edu/~best/ The 20th BEST will take place at the University of Nevada, Las Vegas during June 16–19, 2013, as part of the 94th Annual Meeting of the AAAS Pacific Division.
Please email me or Marion Scheepers for further details, and let people who may be interested know. We expect we will be able to offer some (limited) financial support for students and postdocs. I will be posting more details as they materialize.
