I might put together one for my reference eliminating the standard internet usage terms since I have those down pretty well... plus a few that are missing like E2E (EtE??) for edge to edge, or RxR/Row by Row, and a few others that maybe are regional or not wide spread yet.
It's interesting to me how language and usage evolves, especially with technology. So to use a formally well known and now rather obscure ending --
TTFN! (ta ta for now!)
