Have you read [the rules in the blog](http://blog.stackoverflow.com/2009/08/new-question-asker-features/)? If not, you should.

- The user must have asked at least 3 questions already.
- Questions must not be community wiki.
- Questions must be older than 3 days.
- Questions must have at least 1 answer. 

(one final caveat: accept rate is going to be less meaningful here on meta than elsewhere, just because of the nature of meta..)
