JDN,
If you put the "PZ" code in the name of your event, it sets up a PIN on that event. This is normally used for events published by Administrators, to keep the event confidential until the start time.
http://maprunners.weebly.com/event-types.htmlThere is no need to put a PIN on a CheckSites event, as the 6-digit CheckSites code is private to you.
In fact, the problem then becomes, that the Administration System has not been used to create the event, and it is this system that tells the owner of the event what the PIN is.
So, if you publish a CheckSites event with a PIN, there is no way for you to know what the PIN is.
The simplest remedy is to use CheckSites again and setup a new event with a new name that does not include the PZ code.
