Dear all, This is a reminder that early bird registration for Category Theory 2013 closes TOMORROW, Friday 17th May. After that, the cost of registration goes up by 10% across the board. Any registrations submitted by fax, post or other means at a time verifiably before the 18th in your local timezone will be deemed eligible for the early bird rates; any submitted thereafter will not. The registration page may be found at: http://web.science.mq.edu.au/groups/coact/seminar/ct2013/registration.html If you believe you have submitted a registration form already, but have received no confirmation of its receipt, please email me to let me know.
