Hi Tee,

Do you think this is an appropriate way to treat us?
I'm joking, but really the question is too broad for this list. It's the kind of question one would expect you to ask your advisor. If I answer that, I want to be last author on your paper.
Seriously though: precise, technical questions are much more likely to get answers here.
Cheers,
Jerome
