Become a Gmail Ninja

I am starting by assuming that You are not new to Gmail (beta). I know Gmail has been beta forever, so nothing to miss yet!
Some people have had hard time to migrate to Gmail. I can promise you one thing: Once you jump in, you will love it!!!
So, what is so different about it?

• Threaded Email Inbox
• Label (and move to label) and colorful label
  
• contacts + chat within
• effective spam filter
• easy integration of google calendar and documents.
• and the whole lot of Labs feature!

That is what makes it Beta after such a long time of "public release".

 If you have been using it, how good you are at it?
 Want to see what level do you fit in?
