  Amos and I are proud to announce the first alpha release
  of the O'Reilly Zope Book!  This means that all the chapters

looks like things are "pretty much there",

 Jeffery would like us to take a look at "write locking in zope",
 so that all may edit freely, as long as they don't "interfere with a


PTK Brief

 Albert mentioned that the folks at DataChannel have published a DTD
 aimed at letting portals "interchange content, users, groups, and

 A new version of the PTK should be landing shortly:
 in the meantime, you might grab one of Jim Tittsler's

Zope Web

 Tim has passed the categorization flag on to mindlace, who's working on
it :)

 Shane Hathaway has stalked and killed a memory leak triggered

 our otherwise "eccentric memory usage",
