The glossary does not appear to have been updated in some time. There are a variety of terms and acroynms that are not there (examples that are just TSA related include "TSA" "shoe carnival" "secondary screening" and "SSSS"). There may also be items that are no longer relevant.
Would it be possible to ask for a volunteer from the moderator staff to formally update this list at some point in the near future. Even though I'm not a moderator, I'd be willing to help, but I do not know the guidelines for what makes the cut and what does not.
Thank you for your consideration.
