[nitpick: I left out the work 'adverse' in my last email.]

This is exactly the question that the work party has been wrestling with, and
this situation will hopefully stimulate some useful discussions on the next
call. But to date, we've avoided any specific definition, leaving it up to
the RSOs.

I don't think it's productive to continue debating whether or not my personal
opinion of an event I'm not involved with and have very limited information
about is right or wrong. I encourage everyone to read the document and scope
of work, join future calls and/or make comments on the document if they feel
changes are needed.

Robert
