Hey Valerie and everybody :)
Thanks again for all your detailed great answers, Valerie!!
I just struggled once while reading an explanation around the SignWriting Newspaper.
You wrote ...
Through writing articles in ASL, the Deaf writers learned what they needed to write ASL, and this experience lead to their request for writing Expressively, for writing in vertical columns, and for writing in stacked clusters instead of using stick figures…
Could you please explain what the last one means: writing in stacked clusters instead of using stick figures?
