system upgrade

During the week of May 15-21, the website interface to our database will be down.  You may view information but will not be able to login to access your membership, certification, journal and magazine subscriptions (institutional subscriptions, controlled by IP Address will not be affected) or contact information.  During this time, you are able to initiate an abstract for the 2017 Annual Meeting, but will not be able to finalize it with a payment until May 22.  If you need any assistance during this time, for membership contact us at 608-273-8080 or or for certification/exams contact your representative. Thank you for your patience and understanding as we upgrade our systems to better serve you.
