The test subscribers to the IAA eJournal should have received an email notifying them of Journal 457 being available for download. It is a 4.9MB .pdf file to be downloaded by the subscriber from the IAA website.
Let me know if you have any problems.
NOTE: This is ONLY available to the limited number of people who are in the eJournal test group.
Details on eJournal subscriptions (in place of or addition to hard copy) can be found in the IAA Journal, and will be provided with renewal notices.
