Hoi,<br>I have read the article on Signuno on Wikipedia. It clearly explains why Signuno is not a language. I agree with the argument that as Signuno only tries to make Esperanto visible in signs, it is equivalent to writing Esperanto.
<br><br>Consequently as it is not a language, it does not make sense to consider a language code under the ISO-639-3. It may make sense to include it under ISO-639-6, here it is most likely to get a special status. Signuno may have led to the existence of International Sign, however IS diverged from Signuno and became usable in its own right, it has adopted from many sign languages but is separate from all of them.
