As per the Moderator Pro Tempore blog post, after about a week SE looks for temporary moderators for new sites to help with the development of the community and to act as a liaison between the community and SE.
The recommendations for requirements from that blog post are:
- Have a reasonably high reputation score to indicate active, consistent participation.
- Show an interest in their meta’s community-building activities.
- Lead by example, showing patience and respect for their fellow community members in everything they write.
- Exhibit those intangible traits discussed in A Theory of Moderation.
It's also useful that you have the time to spare for the role, as participation is expected (hoped!) to increase once we are into public beta, and you will be expected to be completely unbiased while fulfilling your moderation duties.
Remember that these positions are only for the duration of the beta, at which point the community should be strong enough to handle full elections.
Anyone within the community is welcome to nominate themselves or others, though please make sure you read the blog post in full beforehand.
For examples of what nominations can look like, take a look at this question from the Raspberry Pi Meta which was posted when that site was at the same stage.
Note: No answer will be chosen on this question at any time. After appointment, the question will be closed.
