Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
I created this account when I asked a question. Now the header at the top says "Stack Exchange" and there is a red rectangle with the number 9; hovering over it says I have 9 unread messages in my Inbox.
So how the hell do I get to the inbox?
Click on the number "9" in the bar at the top. It will expand to show you a list of the messages in your inbox.
