DVInfo Access control is simple. The default settings had to be tightened a bit after spammers started to actually create accounts

• by default, any user can read

• members of AdminGroup have all rights, regardless of ACLs

• members of EditorsGroup have all rights, unless a page is protected by an ACL

  • any user may create an account [:UserPreferences: here]

  • any member of EditorsGroup can add accounts to this group, hence granting write access to a collaegue

• to protect a page, add a line like this at the top:

    #acl YourName:read,write,delete,revert,admin All:read

  • you can do that unless the page is already protected, and you don't have admin rights

Please don't be too restrictive. After all, there's the revert action available, and you can subscribe to email notifications for your pages to get informed when they are changed.

However, do not make pages writable for anonymous users. The spammers are out there.
