This service allows a subscriber to e-mail themselves copies of circulars that they did not receive. In order to use this service you need to know your account number (displayed as the first five digits in the subscriber infomation now contained in the subject line of all issued circulars) and which circulars you missed. Circulars are resent to the e-mail address on file for your account. Note that this service can only be used to resend circulars issued in the past two months or so.

Please note that you should ensure that the reason that you didn't receive these circulars when they were first issued is not one of the following problems.

  • Invalid e-mail address
  • Insufficient disk space
  • Over-zealous spam filter
  • Some other problem local to your site
If one of the above listed problems is the reason you didn't receive the circulars, please ensure that the problem is fixed before you use this service!

In this initial release, only IAUCs may be resent. The resending of MPECs and CBETs will be available in a subsequent release.

If you experience problems, please use the feedback form.
