It has all the words you need to transition, and you can easily get to it from the "TRANS GLOSSARY" link near the top of the right hand menu bar
It includes everything from "AAAMP" - Adult Attracted Minor Person, to "Youngshit Minors" - People that transition very early/before being adults
There are no "Z" words yet because I didn't find any. The trans movement seems to be very zedphobic.
