如果你觉得那些问题该问,那你可以回:
Sorry I have to bother you again, I am a little confused by your answer above. Are you the right person for my questions?If not, could you let me know who is the right POC? Or do you have a mailing list for this kind of questions?
你的问题如果问的太细小,也许他说的是还有其他人可以问,不必问他,他已经有很多人问他关于更大的项目的问题。
