ZH875: The memorable info is there in JPA.
It is used to identify yourself if calling the JPAC, for password resets, or if they want to know who you are.
We were told to input our memorable info when we got the bit of paper with our user name and initial password on from station HR people, around a year or so ago.
Normally, I would assume this was a typical oversight on my part, but the fact that EVERYONE ELSE in my former office, and many others don't know about this, proves otherwise. I'm also a bit of a geek and DID fill in as much of the JPA stuff as I could when we got accounts - and I still don't recall any memorable info.
Perhaps your unit passed on the wise words ...
My post was not really to complain, only to warn others to have their memorable info on the system before they leave and can deal only with the JPAC.
