[Zope] ZWiki, file uploads: how ?

Hi, I was looking at the release notes for ZWiki 0.9.9 and it claims to support file uploads. After looking at http://www.zwiki.org/UploadsModificationDiffs I figured I should add a folder named "uploads" under my ZWiki, set the permissions as defined and I'd be set. I thought that at this point I'd have an [UPLOAD FILE] link or something, like I have with TWiki. Nope. I am browsing the site but documentation on how to enable file uploads is, err, scarce. Anybody out there willing to give some help ? Thanks !! marcio
