I think that pacman/canine/joseph styles are quite easy to discern, IMO.
as far as young ones participating in the CR: yes, I was pretty shocked. (actually, my oldest grandchildren are 6 3/4 y.o., but 9 y.o. technically could be).
do you really think that YWN parents allow their young (under bas/bar mitzvah age) children to read, & possibly post, here in the CR?!
& no, I don’t think it’s appropriate for them to be here.
