* validating cohorts with "Expand cohort to all user’s accounts across projects (via CentralAuth)" does not work.  There's a problem with the database that I can't figure out right now.  If it looks like your cohort should validate and it's not, it's probably not your fault, don't worry about trying again, I'll send out an update if we figure it out.

* some reports seem to fail, but others work, again until we can say with certainty we've fixed this database problem, it'll be hard to say what's happening.
