i saw this on another spot- if it already exists let me know :)

for the "^" part, you answer the question asked by the person above

for the ">" you write something you are doing/thinking/saying

for the "v" you aask a question for the next person

i.e
(if the question above was "who is your favourite character?)

^ Sirius
> i am eating strawberries
v what is your favourite film?
