You can also indicate the copyright date of your version in a reply. For example, the Pre-Anniversary had an 1888 version, and I'm not sure if one before 1902, but also a 1902 Gregg Shorthand Manual. In June 1916, an extensively revised Gregg Shorthand Manual replaced the 1902 Gregg Shorthand Manual. Other's may have come about, and yours may have been copyrighted in another country, you can mention that as well. (Okay, I found that 1902 and 1916 version info from Paul James on his comments on the Alice In Wonderland in Gregg Shorthand. I didn't know that, so I added it here FYI).
I first started with DJS and then moved to Anniversary. Actually at the time I didn't realize it, just know it was older and different. I got rid of my DJS books, which I finished (I thought I was done with Shorthand), then when I needed it again, found the FM manuals at a thrift store.
I'm bringing this back up because Anniversary and Simplified are tied. Please log in and vote. I don't think you can vote on an app or taptalk (not my choice, just the way it is). And you may need to change to view the desktop as opposed to the mobile version.
"Gregg Shorthand had achieved the most extraordinary success ever attained by any system in the history of shorthand." John Robert Gregg, 1922
