You may have been registered for the AAP from the very beginning and in the beginning Griff emailed out the month's schedule. However, each month's schedule is now listed on the site. There's no need to continue to send out emails. Just check out the site each month.
Each month go to the AAP site. The dates and topic for each upcoming session are listed. Use the link to register for all the sessions in that month. Once registered the system will send you reminders.
