[BXXPwg] Draft minutes of meeting in San Diego
Thu, 28 Dec 2000 15:11:37 -0800 (PST)
Thanks for your technical comments. However, I was really looking
for agreement on recording what happened at the meeting. If you
believe that my draft minutes do not reflect what happened, could
you suggest alternative wording.
