Ok Thanks - will contact the relevant people, will put the categories and experts search packages in contrib. WRT 9i we have made all the necessary changes (or so we thought) to all the source but this falls over when we try and install - see this thread
https://openacs.org/forums/message-view?message_id=103520 . The funny thing is if we hook the new code up to 8i it works. We have no Postgress skills so we've not looked at getting these things working with Postgress.
