Thank you for you interest and posts regarding climate change. If you
wish to start a dialog regarding a particular post, please reply to that
individual and not the entire group. We strive to keep the email traffic
manageable so that the pertinent details regarding the CINC program are
not lost in a sea of emails. As always, we do want you to reply all if
you have found a sub for a trip. If you have any questions, please
respond to me directly and thank you for your cooperation.
