Dear Brian,
It is interesting but I should be removed from the mailing list.
All the best,
Mitchell

I'm happy with this report in its current form.
The "looking forward" comment is very sensible. How about a small
competition with cash prize to write a specific piece of
open-source software (python/perl bindings to CIFAPI,
CIF2-compatible update to Perl STAR::Parser, checkCIF module for
magCIF :-)?
