I was doing some experimentation with this feature and I noticed that if a slave site is set to pull user prefs from the master, even if the master side has the user configured for privacy (ie. keep information private - don't show anyone), the slave side will not honour that and will still display that user's information.
I was wondering if this was intended behaviour or if it was a bug or oversight? I don't know a lot about XMLRPC or the InterTiki workings, so wouldn't really know where to start to look at making what I think should be a fix for this. I'm hoping someone else may be able to?
