Arbital's user groups are designed to allow anyone to easily contribute to our growing body of math explanations, while also verifying that every change is positive and assessing page quality to inform readers and bring things to the attention of writers.
Unregistered
Without an account, you can read Arbital pages (and we'll keep track of requisites, with a cookie). This can be pretty fun, but if you want to get more involved you'll need to register.
Registered
With an account you can create new unlisted pages, suggest edits to any page, and directly edit any page you created (including tags, parents, requisites, etc). You can also submit pages to the math domain.
Trusted user
Once you've shown that you can make consistently good edits we'll promote you to trusted user status. At this point, you'll be able to publish your edits directly to all non-locked math pages. [comment: (though, you're still able to suggest changes if you'd like someone to check your work first)]Trusted users also have all editor comments visible by default.
Reviewer
Reviewers monitor the incoming stream of edits, unassessed pages, and submitted pages. They have at least enough domain expertise to know when they need a second opinion and a reasonable understanding of when to assign appropriate meta tags, in particular, Stub/Start/C-Class quality levels and when to support or turn down proposals for A-Class and B-Class.
Reviewers are [comment: able to [arbital_review review and approve / reject edits and pages submitted to a domain. They're] responsible for promoting people to trusted editors and suggesting new reviewers.
The reviewers can be found on #reviews on the Arbital Slack, you're welcome to join and chat to the team or ask for advice on writing and improving pages.
Arbiter
Arbiters provide oversight and dispute resolution to an Arbital domain. They have a strong grasp of the reasons for core policies and processes, can make judgement calls about policy and standards, and are aware that it's usually best to collect alternate opinions before acting.
Arbiters are in charge of selecting and on-boarding new reviewers. They also make decisions about promoting pages to A or B-Class.
