I've been tagged?

So a few days ago, my future sis-in-law, Karen V., tagged me. I had no idea what that meant. Then I read her blog, and she had something about tagging, and answering a lot of questions, and then had my name at the bottom as someone tagged! So...not knowing exactly what I'm doing, I'm just going to copy and paste Karen's questions with my own answers and hope that's what I'm supposed to do. Is there a book on these blogging rules?
