How to configure permissions
Users will need 'View' and 'Access Contents Information' permissions
on the folder to view the wiki. To append comments they will need
'Append to ZWiki Pages' permission. To edit, they will need 'Change
ZWiki Page' permission. To create new pages they will need
'Add ZWiki Page' permission.
Security issues
"You are responsible for security; zwiki may contain unforeseen risks."
ZWiki allows users to create content which will be executed when viewed
by others (DTML, or at least javascript).
If you will be allowing untrusted users to edit your wiki,
you should understand the
ServerSideTrojanIssue.
Tip: to restrict the permissions available to pages at run-time,
ensure that your zwikiweb folder is owned by a low-privileged user.
