i think the importance here is to know what he/she need to do. what is the relationship between him/her with all "ban zhu". and what a "ban zhu" need to do after the guy comes out.
for me, now what i do everyday is (try) to keep coming twice everyday. discuss all the problems i know. mark some as "jing hua" if need. that's all. and i am very busy in my current study. i can not have more time to do more things. i believe most "banzhu" are busy like me. so i do not know such a new guy can do what to benefit us.
