Re: Jabber
The PluginJabber requires the Java jabber client to be copied into your tiki installation.
I did use it on the old damosoft site, but Im in the middle of writing an alternative for the tiki-live-support to integrate into Jabber with jabber.class.php
I have too many things on the go!
Oh I think the plugin jabber requires the jabber server to be sat on the same machine at the tiki too.
