You earn stars when someone stars your question or answer.

* Initially, you can award one star to each post.
* When you reach a total star score of 10, you will be able to award one or two stars to each post.
* When you reach 100 stars, you can award up to three stars.
* ...and so on.

Questions can only be awarded stars if they are *meta* posts (all questions on meta, questions marked as local meta questions on main).

Your total stars are maintained separately on each site.
