DVInfo Access control is simple, and the default settings are rather permissive:

• anonymous users (not logged into their wiki account) can only read

• members of AdminGroup have all rights, regardless of ACLs

• all other known users have all rights, unless a page is secured by an ACL

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

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

    #acl YourName:read,write,delete,revert,admin Known:read,write,revert 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.
