I just sent this email and thought maybe
you should have something like this in
your FAQ database, if you don't already.

Subject: Flyers uploaded to ceder.net

Thank you for uploading flyers to ceder.net
Unfortunately, we cannot do anything with these
until and unless you enter an event into our
Event database. To do so, please go here:
https://www.ceder.net/eventdb/edit.php
fill out the form, choose a PIN to act as a
password so that you can return to modify
the entry as desired. Once you have done this,
you can upload your own flyer to help advertise
your event. Please let me know if you have any
questions. Thank you very much.
