Thank you, Flip, for a nice example of the type of summaries
we like to see on the Bulletin Board. It even has the word
'summary' in the subject line, which is the first word I hunt
for when I start making the 'Recent Bulletin Board Discussions'
entry for the CCP4 Newsletter. Depending on how much time I
have to search through the archives, other postings may never
make it to this coveted publication. Please, can I have more
of this type of summary?

Thanks, everyone,
Maria Turkenburg
