Hi everyone,
Nathan Rutman from Xyratex attended the call, and I was there as well
(although I confess I'm not sure if I spoke up enough to be
recognized). Can we please get added to the list in the notes? I
want to make sure our management knows we were there! Perhaps in the
future we could go over the list at the end of the call to make sure
no one was missed? Or is there a better way to make sure we get
everyone?
btw I was very encouraged to hear someone on the call spoke up and
offered to share some work that Joshua might be interested in - this
is exactly the kind of collaboration the board wanted to encourage by
asking for regular meetings to be held. I enjoyed the discussions and
look forward to the next call.
Thanks,
Meghan
