Arbital user groups

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.


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.


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. (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.


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 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.


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.
