What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates

This is supported by the fact that yesterday around 19.00 GMT I got an email saying that I did fulfill my commitment for the Statistical Analyses Site.
