From a pm message on reddit

 
I don't know your level of technical knowledge so forgive me if this is ether incomprehensible or patronising. 

The software the wiki runs on is an open source package https://www.dokuwiki.org/dokuwiki#

What I'm describing here is my attempt at a precise of the relevant bits of https://www.dokuwiki.org/manual. I'm not a technical writer so if I don't make sense you may do better reading the manual

Dokuwiki has pages and namespaces. Namespaces are a bit like folders and can contain other namespaces in a tree like hierarchy https://www.dokuwiki.org/namespaces.

It users users, groups, access control lists (ACLs) and privileges. 

Users are assigned to groups to allow for easier administration. 

The privileges are, in ascending order none, read, edit, create, upload and delete. Groups and users with higher privileges have all the lower privileges 

Name  | Applies to | Permission
---|---|---
| none    | pages, namespaces  | no permission---complete lock out  
| read    |  pages, namespaces  | read permission  
| edit    |  pages, namespaces  | existing pages may be edited 
| create  | namespaces | new pages can be created 
| upload  | namespaces | mediafiles may be uploaded
| delete  |  16   | namespaces | mediafiles may be overwritten or deleted | AUTH_DELETE  |
| admin   |  255  | admin plugins  | superuser((see [[config:superuser]])) can change admin settings  | AUTH_ADMIN |

Dokuwiki has a setting, superuser, that defines who has the ability to change ACLs and assign users to groups.

**Allowing Moderation**

By default most users can have upload access to all pages. This will allow them to create and edit pages and namespaces. If we assume that most users are friendly any low volume vandalism can be deal with by contributors deleting offensive content. 

Dokuwiki keeps and allows access to the full history of changes to all pages. This means that if valued content is deleted it can be bought back  by any user.

Most moderation can be done by the community of users. However if a concerted attack happens it may be necessary moderators will need to remove permissions from disruptive users. 

At the moment only superusers have the ability to do this, they also have the ability to delete other superusers and take over the entire wiki. 

I have found an add in https://www.dokuwiki.org/plugin:groupmanager that will allow users to assigned to an moderator group (wg_mygroup_admin in the above ref) that will be able to control other users access to ediit the wiki. 

The plugin documentation is a bit difficult to get your head round (well, it was for me). I've got my head round it and have worked out how to use it on a play pen wiki on my own pc. It would take me a lot longer to explain it in english than it would to set it up along with a few 'playpen' accounts for people to explore themselves. 

**Notifications.**

Dokuwiki can be set up to send an email message for every change done to a notification email address. This email could be set up to forward all messages to the moderators so they would be aware of any unusual patterns or attacks. 

If the volume of changes makes this impracticable dokuwiki can also support RSS feeds that moderators could subscribe to. 

Does any of this make sense to anyone?
