EDIT: To answer @foggyone's question, the most important thing, at the moment, is to get your commiters to participate in other StackExchange sites.
As you can see, we've got 109 more commiters than we need. But only 36 have 200+ reputation on at least one site.
This way, the user score will rocket up, in addition to the number of users with 200+ reputation. Win-Win-Win.
