I've taken notes in an alphabetic-based shorthand for about 20 years, but recently decided to learn Teeline Shorthand (which is relatively unknown in the US, although I hear it is still quite popular in the UK). While I was looking around for resources, I came across a site devoted to Gregg shorthand, with an interesting little bonus attached.

HERE is a link to a page which contains several Gregg shorthand manuals. Down near the bottom is a textbook from 1918 which adopts Gregg shorthand to Esperanto!

Teeline is a much simpler system than Gregg, so I haven't bothered to delve into the textbook beyond the first few pages. But it was a really unexpected find.

I at one time learnt Gregg for English (actually before I began Esperanto!), though I never was able to fully exploit it. Thanks for pointing this out to me! I had given up on Gregg, but maybe I’ll look into the Esperanto version.

I’m sure it actually works better than its English equivalent, as with Tengwar k.t.p. (By the way, if anyone wants to see my phonetic Tengwar mode for English, I’ll see if I can send it)
