  A new pseudospectral calculation of collapsing Euler vortices \cite{HouLi06}
has called into question the long-term conclusions of singular behavior
described earlier in \cite{Kerr93,Kerr05}. This review is designed to: improve
the discussion of the detailed analysis of one test initial condition designed
find sources of errors, to compare that with calculations showing no evidence
of a singularity, and to document two sets of discussions. Those prior to 1993
between competing teams. And recent discussions of what is needed to reach more
convincing conclusions.
