What does this mean?

I am now the official senior developer as Bin is now gone. I got an E-mail from Chris. He said “remember when I told you to get all the hard bug questions asked of Bin before she left? I hope you did it. You’re now the man.” I wasn’t quite sure how to take that E-mail.

I worked on figuring out the flow of the pricing pages. I got it documented. I did not get very far with the bug though. But I did determine that these are not really bugs. The stuff was never completed. So I am not fixing things that did not work correctly. I actually was finishing the programming off.
