[Zope] Membership Install & ZCatalog

It appears that the Membership product will no longer install under 2.3.0 due to a ZCatalog bug. Specifically, attempting to paste (or manage_clone) a ZCatalog fails with the message "The object MemberCatalog does not support this operation." Since Membership include a ZCatalog, this bug prevents it from installing under 2.3.0. Now, I'm a bit new to all this, but I'm guessing that Digital Creations should be informed about this since ZCatalog is a core Zope product. How do I go about reporting a bug? -- Ed Goppelt
