I'll be having a talk with a lecturer from a postgrad course that I'm potentially going for. I'm not sure how such things are conducted in NZ. Is it typically just an informal 'talk', in which I would just show up dressed however I like, and 'talk'? Also, how does one usually address such people here? (He has a PhD, but isn't a professor). Are first names usually used?
Also, I already have an offer from another university for the same course. Would it be wise to mention it, or otherwise?
