Hidden among the piles of documents filed with the Postal Rate Commission is one that I hadn’t seen in a long time- the “Glossary of Postal Terms“.

Don’t know the difference between a RAP and the RAPS? Can’t remember what makes a container an ERMC rather than a GPMC? It’s all here, and more. Remember ‘Activity Based Management’? No, I didn’t think so. How about ‘M-bags’?

And along the way you’ll find ‘pie-cart’, ‘killer bars’, ‘lawn crossing’, ’7:01 rule’, and my favorite from the days of the LSM: ‘smiles, frowns, and upside downs’.
